Hello Friends ............ What is Music,Music directors,Musical Instruments? Music is an art form whose medium is sound. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").[1] In its most general form the activities describing music as an art form include the production of works of music, the criticism of music, the study of the history of music, and the aesthetic dissemination of music. The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to personal interpretation, and occasionally controversial. Within the arts, music may be classified as a performing art, a fine art, and auditory art. It may also be divided among art music and folk music. There is also a strong connection between music and mathematics.[2] Music may be played and heard live, may be part of a dramatic work or film, or may be recorded. To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."[3] Contents [hide] 1 Etymology 2 Music as form of art 2.1 Composition 2.2 Notation 2.3 Improvisation 2.4 Theory 3 History 3.1 Prehistoric eras 3.2 Ancient Egypt 3.3 Asian cultures 3.4 References in the Bible 3.5 Antiquity 3.5.1 Ancient Greece 3.6 The Middle Ages 3.7 The Renaissance 3.8 The Baroque 3.9 Classicism 3.10 Romanticism 3.11 20th- and 21st-century music 4 Performance 4.1 Aural tradition 4.2 Ornamentation 5 Philosophy and aesthetics 6 Psychology 6.1 Cognitive neuroscience of music 6.2 Cognitive musicology 6.3 Psychoacoustics 6.4 Evolutionary musicology 6.5 Culture in music cognition 7 Sociology 8 Media and technology 8.1 Internet 9 Business 10 Education 10.1 Non-professional 10.2 Academia 10.3 Ethnomusicology 11 Music therapy 12 See also 13 References 14 Further reading 15 External links Etymology The word derives from Greek μουσική (mousike; "art of the Muses").[1] Music as form of art Jean-Gabriel Ferlan performing at a 2008 concert at the collège-lycée Saint-François Xavier Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. Amateur musicians compose and perform music for their own pleasure, and they do not derive their income from music. Professional musicians are employed by a range of institutions and organisations, including armed forces, churches and synagogues, symphony orchestras, broadcasting or film production companies, and music schools. Professional musicians sometimes work as freelancers, seeking contracts and engagements in a variety of settings. There are often many links between amateur and professional musicians. Beginning amateur musicians take lessons with professional musicians. In community settings, advanced amateur musicians perform with professional musicians in a variety of ensembles, such as concert bands, orchestras, and other ensembles. In some cases, amateur musicians attain a professional level of competence, and they are able to perform in professional performance settings. A distinction is often made between music performed for the benefit of a live audience and music that is performed for the purpose of being recorded and distributed through the music retail system or the broadcasting system. However, there are also many cases where a live performance in front of an audience is recorded and distributed (or broadcast). Composition Main article: Musical composition The composer Michel Richard Delalande, pen in hand. "Composition" is often classed as the creation and recording of music via a medium by which others can interpret it (i.e., paper or sound). Many cultures use at least part of the concept of preconceiving musical material, or composition, as held in western classical music. Even when music is notated precisely, there are still many decisions that a performer has to make. The process of a performer deciding how to perform music that has been previously composed and notated is termed interpretation. Different performers' interpretations of the same music can vary widely. Composers and song writers who present their own music are interpreting, just as much as those who perform the music of others or folk music. The standard body of choices and techniques present at a given time and a given place is referred to as performance practice, whereas interpretation is generally used to mean either individual choices of a performer, or an aspect of music that is not clear, and therefore has a "standard" interpretation. In some musical genres, such as jazz and blues, even more freedom is given to the performer to engage in improvisation on a basic melodic, harmonic, or rhythmic framework. The greatest latitude is given to the performer in a style of performing called free improvisation, which is material that is spontaneously "thought of" (imagined) while being performed, not preconceived. Improvised music usually follows stylistic or genre conventions and even "fully composed" includes some freely chosen material. Composition does not always mean the use of notation, or the known sole authorship of one individual. Music can also be determined by describing a "process" that creates musical sounds. Examples of this range from wind chimes, through computer programs that select sounds. Music from random elements is called Aleatoric music, and is associated with such composers as John Cage, Morton Feldman, and Witold Lutosławski. Music can be composed for repeated performance or it can be improvised: composed on the spot. The music can be performed entirely from memory, from a written system of musical notation, or some combination of both. Study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition is broad enough to include spontaneously improvised works like those of free jazz performers and African drummers such as the Ewe drummers. Notation Main article: Musical notation Sheet music is written representation of music. This is a homorhythmic (i.e., hymn-style) arrangement of a traditional piece entitled "Adeste Fideles", in standard two-staff format for mixed voices. Play (help·info) Notation is the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music is notated, along with instructions on how to perform the music. The study of how to read notation involves music theory, harmony, the study of performance practice, and in some cases an understanding of historical performance methods. Written notation varies with style and period of music. In Western Art music, the most common types of written notation are scores, which include all the music parts of an ensemble piece, and parts, which are the music notation for the individual performers or singers. In popular music, jazz, and blues, the standard musical notation is the lead sheet, which notates the melody, chords, lyrics (if it is a vocal piece), and structure of the music. Scores and parts are also used in popular music and jazz, particularly in large ensembles such as jazz "big bands." In popular music, guitarists and electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates the location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tabulature was also used in the Baroque era to notate music for the lute, a stringed, fretted instrument. Notated music is produced as sheet music. To perform music from notation requires an understanding of both the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or a genre. In improvisation, the performer often plays from music where only the chord changes are written, requiring a great understanding of the music's structure and chord progressions. Improvisation Main article: Musical improvisation Musical improvisation is the creation of spontaneous music. Improvisation is often considered an act of instantaneous composition by performers, where compositional techniques are employed with or without preparation. Improvisation is a major part of some types of music, such as blues, jazz, and jazz fusion, in which instrumental performers improvise solos and melody lines. In the Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era; solo performers and singers improvised virtuoso cadenzas during concerts. However, in the 20th and 21st century, improvisation played a smaller role in Western Art music. In Indian classical music, spontaneous improvisation is a core component and an essential criteria of any performance. Theory Main article: Music theory Music theory encompasses the nature and mechanics of music. It often involves identifying patterns that govern composers' techniques and examining the language and notation of music. In a grand sense, music theory distills and analyzes the parameters or elements of music – rhythm, harmony (harmonic function), melody, structure, form, and texture. Broadly, music theory may include any statement, belief, or conception of or about music.[4] People who study these properties are known as music theorists. Some have applied acoustics, human physiology, and psychology to the explanation of how and why music is perceived. Music has many different fundamentals or elements. These are, but are not limited to: pitch, beat or pulse, rhythm, melody, harmony, texture, allocation of voices, timbre or color, expressive qualities (dynamics and articulation), and form or structure. Pitch is a subjective sensation, reflecting generally the lowness or highness of a sound. Rhythm is the arrangement of sounds and silences in time. Meter animates time in regular pulse groupings, called measures or bars. A melody is a series of notes sounding in succession. The notes of a melody are typically created with respect to pitch systems such as scales or modes. Harmony is the study of vertical sonorities in music. Vertical sonority refers to considering the relationships between pitches that occur together; usually this means at the same time, although harmony can also be implied by a melody that outlines a harmonic structure. Notes can be arranged into different scales and modes. Western music theory generally divides the octave into a series of 12 notes that might be included in a piece of music. In music written using the system of major-minor tonality, the key of a piece determines the scale used. Musical texture is the overall sound of a piece of music commonly described according to the number of and relationship between parts or lines of music: monophony, heterophony, polyphony, homophony, or monody. Timbre, sometimes called "Color" or "Tone Color" is the quality or sound of a voice or instrument.[5] Expressive Qualities are those elements in music that create change in music that are not related to pitch, rhythm or timbre. They include Dynamics and Articulation. Form is a facet of music theory that explores the concept of musical syntax, on a local and global level. Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Popular Music often makes use of strophic form often in conjunction with Twelve bar blues. Analysis is the effort to describe and explain music. History Further information: History of music Prehistoric eras Main article: Prehistoric music Prehistoric music can only be theorized based on findings from paleolithic archaeology sites. Flutes are often discovered, carved from bones in which lateral holes have been pierced; these are thought to have been blown at one end like the Japanese shakuhachi. The Divje Babe flute, carved from a cave bear femur, is thought to be at least 40,000 years old. Instruments such as the seven-holed flute and various types of stringed instruments, such as the Ravanahatha, have been recovered from the Indus Valley Civilization archaeological sites.[6] India has one of the oldest musical traditions in the world—references to Indian classical music (marga) are found in the Vedas, ancient scriptures of the Hindu tradition.[7] The earliest and largest collection of prehistoric musical instruments was found in China and dates back to between 7000 and 6600 BC.[8] The Hurrian song, found on clay tablets that date back to approximately 1400 BC, is the oldest surviving notated work of music. Ancient Egypt Main article: Music of Egypt Musicians of Amun, Tomb of Nakht, 18th Dynasty, Western Thebes The ancient Egyptians credited one of their gods, Thoth, with the invention of music, with Osiris in turn used as part of his effort to civilize the world. The earliest material and representational evidence of Egyptian musical instruments dates to the Predynastic period, but the evidence is more securely attested in the Old Kingdom when harps, flutes and double clarinets were played.[9] Percussion instruments, lyres and lutes were added to orchestras by the Middle Kingdom. Cymbals[10] frequently accompanied music and dance, much as they still do in Egypt today. Egyptian folk music, including the traditional Sufi dhikr rituals, are the closest contemporary music genre to ancient Egyptian music, having preserved many of its features, rhythms and instruments.[11][12] Asian cultures Indian women dressed in regional attire playing a variety of musical instruments popular in different parts of India Gangubai Hangal Durga See also: Music of Iran, Music of Afghanistan, Music of Tajikistan, Music of Sri Lanka and Music of Uzbekistan Indian classical music is one of the oldest musical traditions in the world.[13] The Indus Valley civilization has sculptures that show dance[14] and old musical instruments, like the seven holed flute. Various types of stringed instruments and drums have been recovered from Harrappa and Mohenjo Daro by excavations carried out by Sir Mortimer Wheeler.[15] The Rigveda has elements of present Indian music, with a musical notation to denote the metre and the mode of chanting.[16] Indian classical music (marga) is monophonic, and based on a single melody line or raga rhythmically organized through talas.Silappadhikaram by Ilango Adigal gives so much information about how new scale can be formed by modal shift of tonic from existing scale.[17] Hindustani music was influenced by the Persian performance practices of the Afghan Mughals. Carnatic music popular in the southern states, is largely devotional; the majority of the songs are addressed to the Hindu deities. There are a lot of songs emphasising love and other social issues. Asian music covers the music cultures of Arabia, Central Asia, East Asia, South Asia, and Southeast Asia. Chinese classical music, the traditional art or court music of China, has a history stretching over around three thousand years. It has its own unique systems of musical notation, as well as musical tuning and pitch, musical instruments and styles or musical genres. Chinese music is pentatonic-diatonic, having a scale of twelve notes to an octave (5 + 7 = 12) as does European-influenced music. Persian music is the music of Persia and Persian language countries: musiqi, the science and art of music, and muzik, the sound and performance of music (Sakata 1983). References in the Bible Main article: History of music in the biblical period "David with his harp" Paris Psalter, c. 960, Constantinople Music and theatre scholars studying the history and anthropology of Semitic and early Judeo-Christian culture have discovered common links in theatrical and musical activity between the classical cultures of the Hebrews and those of later Greeks and Romans. The common area of performance is found in a "social phenomenon called litany," a form of prayer consisting of a series of invocations or supplications. The Journal of Religion and Theatre notes that among the earliest forms of litany, "Hebrew litany was accompanied by a rich musical tradition:"[18] "While Genesis 4.21 identifies Jubal as the "father of all such as handle the harp and pipe," the Pentateuch is nearly silent about the practice and instruction of music in the early life of Israel. Then, in I Samuel 10 and the texts that follow, a curious thing happens. "One finds in the biblical text," writes Alfred Sendrey, "a sudden and unexplained upsurge of large choirs and orchestras, consisting of thoroughly organized and trained musical groups, which would be virtually inconceivable without lengthy, methodical preparation." This has led some scholars to believe that the prophet Samuel was the patriarch of a school, which taught not only prophets and holy men, but also sacred-rite musicians. This public music school, perhaps the earliest in recorded history, was not restricted to a priestly class—which is how the shepherd boy David appears on the scene as a minstrel to King Saul."[18] Antiquity Western cultures have had a major influence on the development of music. The history of the music of the Western cultures can be traced back to Ancient Greece times. Ancient Greece Music was an important part of social and cultural life in Ancient Greece. Musicians and singers played a prominent role in Greek theater.[19] Mixed-gender choruses performed for entertainment, celebration, and spiritual ceremonies.[20] Instruments included the double-reed aulos and a plucked string instrument, the lyre, principally the special kind called a kithara. Music was an important part of education, and boys were taught music starting at age six. Greek musical literacy created a flowering of music development. Greek music theory included the Greek musical modes, that eventually became the basis for Western religious and classical music. Later, influences from the Roman Empire, Eastern Europe, and the Byzantine Empire changed Greek music. The Seikilos epitaph is the oldest surviving example of a complete musical composition, including musical notation, from anywhere in the world. The Middle Ages Léonin or Pérotin Breves dies hominis The medieval era (476 to 1400) started with the introduction of chanting into Roman Catholic Church services. Western Music then started becoming more of an art form with the advances in music notation. The only European Medieval repertory that survives from before about 800 is the monophonic liturgical plainsong of the Roman Catholic Church, the central tradition of which was called Gregorian chant. Alongside these traditions of sacred and church music there existed a vibrant tradition of secular song. Examples of composers from this period are Léonin, Pérotin and Guillaume de Machaut. The Renaissance T.L. de Victoria Amicus meus Allegory of Music, by Filippino Lippi Renaissance music (c. 1400 to 1600) was more focused on secular themes. Around 1450, the printing press was invented, and that helped to disseminate musical styles more quickly and across a larger area. Thus, music could play an increasingly important role in daily life. Musicians worked for the church, courts and towns. Church choirs grew in size, and the church remained an important patron of music. By the middle of the 15th century, composers wrote richly polyphonic sacred music. Prominent composers from this era are Guillaume Dufay, Giovanni Pierluigi da Palestrina, Thomas Morley, and Orlande de Lassus. However, musical activity shifted to the courts. Kings and princes competed for the finest composers. Many leading important composers came from the Netherlands, Belgium, and northern France and are called the Franco-Flemish composers. They held important positions throughout Europe, especially in Italy. Other countries with vibrant musical lives include Germany, England, and Spain. The Baroque J.S. Bach Toccata and Fugue The Baroque era of music took place from 1600 to 1750, as the Baroque artistic style flourished across Europe; and during this time, music expanded in its range and complexity. Baroque music began when the first operas were written and when contrapuntal music became prevalent. German Baroque composers wrote for small ensembles including strings, brass, and woodwinds, as well as choirs, pipe organ, harpsichord, and clavichord. During this period several major music forms were defined that lasted into later periods when they were expanded and evolved further, including the fugue, the invention, the sonata, and the concerto.[21] The late Baroque style was polyphonically complex and ornamental and rich in its melodies. Composers from the Baroque era include Johann Sebastian Bach, George Frideric Handel, and Georg Philipp Telemann. Classicism W.A. Mozart Symphony 40 g-moll The music of the Classical Period (1750 to 1830) looked to the art and philosophy of Ancient Greece and Rome, to the ideals of balance, proportion and disciplined expression. It has a lighter, clearer and considerably simpler texture, and tended to be almost voicelike and singable. New genres were discovered. The main style was the homophony,[22] where prominent melody and accompaniment are clearly distinct. Importance was given to instrumental music. It was dominated by further evolution of musical forms initially defined in the Baroque period: the sonata, the concerto, and the symphony. Others main kinds were trio, string quartet, serenade and divertimento. The sonata was the most important and developed form. Although Baroque composers also wrote sonatas, the Classical style of sonata is completely distinct. All of the main instrumental forms of the Classical era were based on the dramatic structure of the sonata. One of the most important evolutionary steps made in the Classical period was the development of public concerts. The aristocracy would still play a significant role in the sponsorship of musical life, but it was now possible for composers to survive without being its permanent employees. The increasing popularity led to a growth in both the number and range of the orchestras. The expansion of orchestral concerts necessitated large public spaces. As a result of all these processes, symphonic music (including opera, ballet and oratorio) became more extroverted. The best known composers of Classicism are Carl Philipp Emanuel Bach, Christoph Willibald Gluck, Johann Christian Bach, Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven and Franz Schubert. Beethoven and Schubert are also considered to be composers in evolution towards Romanticism. Romanticism R. Wagner Die Walküre Romantic music (c. 1810 to 1900) turned the rigid styles and forms of the Classical era into more passionate and expressive pieces. It attempted to increase emotional expression and power to describe deeper truths or human feelings. The emotional and expressive qualities of music came to take precedence over technique and tradition. Romantic composers grew in idiosyncrasy, and went further in the syncretism of different art-forms (such as literature), history (historical figures), or nature itself with music. Romantic love was a prevalent theme in many works composed during this period. In some cases the formal structures from the classical period were preserved, but in many others existing genres, forms, and functions were improved. Also, new forms were created that were deemed better suited to the new subject matter. Opera and ballet continued to evolve.[19] In 1800, the music developed by Ludwig van Beethoven and Franz Schubert introduced a more dramatic, expressive style. In Beethoven's case, motifs, developed organically, came to replace melody as the most significant compositional unit. Later Romantic composers such as Pyotr Ilyich Tchaikovsky, Antonín Dvořák, and Gustav Mahler used more elaborated chords and more dissonance to create dramatic tension. They generated complex and often much longer musical works. During Romantic period tonality was at its peak. The late 19th century saw a dramatic expansion in the size of the orchestra, and in the role of concerts as part of urban society. It also saw a new diversity in theatre music, including operetta, and musical comedy and other forms of musical theatre.[19] 20th- and 21st-century music Main article: 20th-century music Double bassist Reggie Workman, tenor saxophone player Pharoah Sanders, and drummer Idris Muhammad performing in 1978 With 20th-century music, there was a vast increase in music listening as the radio gained popularity and phonographs were used to replay and distribute music. The focus of art music was characterized by exploration of new rhythms, styles, and sounds. Igor Stravinsky, Arnold Schoenberg, and John Cage were all influential composers in 20th-century art music. The invention of sound recording and the ability to edit music gave rise to new subgenre of classical music, including the acousmatic [23] and Musique concrète schools of electronic composition. Jazz evolved and became an important genre of music over the course of the 20th century, and during the second half of that century, rock music did the same. Jazz is an American musical artform that originated in the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note.[24] From its early development until the present, jazz has also incorporated music from 19th- and 20th-century American popular music.[25] Jazz has, from its early-20th-century inception, spawned a variety of subgenres, ranging from New Orleans Dixieland (1910s) to 1970s and 1980s-era jazz-rock fusion. Rock music is a genre of popular music that developed in the 1960s from 1950s rock and roll, rockabilly, blues, and country music.[26] The sound of rock often revolves around the electric guitar or acoustic guitar, and it uses a strong back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, analog synthesizers and digital ones and computers since the 1990s. Along with the guitar or keyboards, saxophone and blues-style harmonica are used as soloing instruments. In its "purest form," it "has three chords, a strong, insistent back beat, and a catchy melody."[27] In the late 1960s and early 1970s, it branched out into different subgenres, ranging from blues rock and jazz-rock fusion to heavy metal and punk rock, as well as the more classical influenced genre of progressive rock and several types of experimental rock genres. Performance Main article: Performance Chinese Naxi musicians Performance is the physical expression of music. Often, a musical work is performed once its structure and instrumentation are satisfactory to its creators; however, as it gets performed, it can evolve and change. A performance can either be rehearsed or improvised. Improvisation is a musical idea created without premeditation, while rehearsal is vigorous repetition of an idea until it has achieved cohesion. Musicians will sometimes add improvisation to a well-rehearsed idea to create a unique performance. Many cultures include strong traditions of solo and performance, such as in Indian classical music, and in the Western art-music tradition. Other cultures, such as in Bali, include strong traditions of group performance. All cultures include a mixture of both, and performance may range from improvised solo playing for one's enjoyment to highly planned and organised performance rituals such as the modern classical concert, religious processions, music festivals or music competitions. Chamber music, which is music for a small ensemble with only a few of each type of instrument, is often seen as more intimate than symphonic works. Aural tradition Many types of music, such as traditional blues and folk music were originally preserved in the memory of performers, and the songs were handed down orally, or aurally (by ear). When the composer of music is no longer known, this music is often classified as "traditional." Different musical traditions have different attitudes towards how and where to make changes to the original source material, from quite strict, to those that demand improvisation or modification to the music. A culture's history may also be passed by ear through song. Ornamentation Main article: Ornament (music) In a score or on a performer's music part, this sign indicates that the musician should perform a trill—a rapid alternation between two notes. Play (help·info) The detail included explicitly in the music notation varies between genres and historical periods. In general, art music notation from the 17th through the 19th century required performers to have a great deal of contextual knowledge about performing styles. For example, in the 17th and 18th century, music notated for solo performers typically indicated a simple, unadorned melody. However, performers were expected to know how to add stylistically appropriate ornaments, such as trills and turns. In the 19th century, art music for solo performers may give a general instruction such as to perform the music expressively, without describing in detail how the performer should do this. The performer was expected to know how to use tempo changes, accentuation, and pauses (among other devices) to obtain this "expressive" performance style. In the 20th century, art music notation often became more explicit and used a range of markings and annotations to indicate to performers how they should play or sing the piece. In popular music and jazz, music notation almost always indicates only the basic framework of the melody, harmony, or performance approach; musicians and singers are expected to know the performance conventions and styles associated with specific genres and pieces. For example, the "lead sheet" for a jazz tune may only indicate the melody and the chord changes. The performers in the jazz ensemble are expected to know how to "flesh out" this basic structure by adding ornaments, improvised music, and chordal accompaniment. Philosophy and aesthetics Main articles: Philosophy of music and Aesthetics of music Philosophy of music is the study of fundamental questions regarding music. The philosophical study of music has many connections with philosophical questions in metaphysics and aesthetics. Some basic questions in the philosophy of music are: What is the definition of music? (What are the necessary and sufficient conditions for classifying something as music?) What is the relationship between music and mind? What does musical history reveal to us about the world? What is the connection between music and emotions? What is meaning in relation to music? Traditionally, the aesthetics of music explored the mathematical and cosmological dimensions of rhythmic and harmonic organization. In the eighteenth century, focus shifted to the experience of hearing music, and thus to questions about its beauty and human enjoyment (plaisir and jouissance) of music. The origin of this philosophic shift is sometimes attributed to Baumgarten in the 18th century, followed by Kant. Through their writing, the ancient term 'aesthetics', meaning sensory perception, received its present day connotation. In recent decades philosophers have tended to emphasize issues besides beauty and enjoyment. For example, music's capacity to express emotion has been a central issue. In the 20th century, important contributions were made by Peter Kivy, Jerrold Levinson, Roger Scruton, and Stephen Davies. However, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. In the 19th century, a significant debate arose between Eduard Hanslick, a music critic and musicologist, and composer Richard Wagner. Harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales. Also many modern composers like Lamonte Young, Rhys Chatham and Glenn Branca paid much attention to a scale called just intonation. It is often thought that music has the ability to affect our emotions, intellect, and psychology; it can assuage our loneliness or incite our passions. The philosopher Plato suggests in the Republic that music has a direct effect on the soul. Therefore, he proposes that in the ideal regime music would be closely regulated by the state. (Book VII) There has been a strong tendency in the aesthetics of music to emphasize the paramount importance of compositional structure; however, other issues concerning the aesthetics of music include lyricism, harmony, hypnotism, emotiveness, temporal dynamics, resonance, playfulness, and color (see also musical development). Psychology Main article: Music psychology Modern music psychology aims to explain and understand musical behavior and experience.[28] Research in this field and its subfields are primarily empirical; their knowledge tends to advance on the basis of interpretations of data collected by systematic observation of and interaction with human participants. In addition to its focus on fundamental perceptions and cognitive processes, music psychology is a field of research with practical relevance for many areas, including music performance, composition, education, criticism, and therapy, as well as investigations of human aptitude, skill, intelligence, creativity, and social behavior. Cognitive neuroscience of music Main article: Cognitive neuroscience of music The primary auditory cortex is one of the main areas associated with superior pitch resolution. Cognitive neuroscience of music is the scientific study of brain-based mechanisms involved in the cognitive processes underlying music. These behaviours include music listening, performing, composing, reading, writing, and ancillary activities. It also is increasingly concerned with the brain basis for musical aesthetics and musical emotion. The field is distinguished by its reliance on direct observations of the brain, using such techniques as functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), magnetoencephalography (MEG), electroencephalography (EEG), and positron emission tomography (PET). Cognitive musicology Main article: Cognitive musicology Cognitive musicology is a branch of cognitive science concerned with computationally modeling musical knowledge with the goal of understanding both music and cognition.[29] The use of computer models provides an exacting, interactive medium in which to formulate and test theories and has roots in artificial intelligence and cognitive science.[30] This interdisciplinary field investigates topics such as the parallels between language and music in the brain. Biologically inspired models of computation are often included in research, such as neural networks and evolutionary programs.[31] This field seeks to model how musical knowledge is represented, stored, perceived, performed, and generated. By using a well-structured computer environment, the systematic structures of these cognitive phenomena can be investigated.[32] Psychoacoustics Main article: Psychoacoustics Further information: Hearing (sense) Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound (including speech and music). It can be further categorized as a branch of psychophysics. Evolutionary musicology Main article: Evolutionary musicology Evolutionary musicology concerns the "origins of music, the question of animal song, selection pressures underlying music evolution", and "music evolution and human evolution".[33] It seeks to understand music perception and activity in the context of evolutionary theory. Charles Darwin speculated that music may have held an adaptive advantage and functioned as a protolanguage,[34] a view which has spawned several competing theories of music evolution.[35][36][37] An alternate view sees music as a by-product of linguistic evolution; a type of "auditory cheesecake" that pleases the senses without providing any adaptive function.[38] This view has been directly countered by numerous music researchers.[39][40][41] Culture in music cognition Main article: Culture in music cognition See also: Ethnomusicology An individual's culture or ethnicity plays a role in their music cognition, including their preferences, emotional reaction, and musical memory. Musical preferences are biased toward culturally familiar musical traditions beginning in infancy, and adults' classification of the emotion of a musical piece depends on both culturally specific and universal structural features.[42][43] Additionally, individuals' musical memory abilities are greater for culturally familiar music than for culturally unfamiliar music.[44][45] Sociology Main article: Sociomusicology This Song Dynasty (960–1279) painting, entitled the "Night Revels of Han Xizai," shows Chinese musicians entertaining guests at a party in a 10th-century household. Many ethnographic studies demonstrate that music is a participatory, community-based activity.[46][47] Music is experienced by individuals in a range of social settings ranging from being alone to attending a large concert, forming a music community, which cannot be understood as a function of individual will or accident; it includes both commercial and non-commercial participants with a shared set of common values. Musical performances take different forms in different cultures and socioeconomic milieus. In Europe and North America, there is often a divide between what types of music are viewed as a "high culture" and "low culture." "High culture" types of music typically include Western art music such as Baroque, Classical, Romantic, and modern-era symphonies, concertos, and solo works, and are typically heard in formal concerts in concert halls and churches, with the audience sitting quietly in seats. Other types of music—including, but not limited to, jazz, blues, soul, and country—are often performed in bars, nightclubs, and theatres, where the audience may be able to drink, dance, and express themselves by cheering. Until the later 20th century, the division between "high" and "low" musical forms was widely accepted as a valid distinction that separated out better quality, more advanced "art music" from the popular styles of music heard in bars and dance halls. However, in the 1980s and 1990s, musicologists studying this perceived divide between "high" and "low" musical genres argued that this distinction is not based on the musical value or quality of the different types of music.[citation needed] Rather, they argued that this distinction was based largely on the socioeconomics standing or social class of the performers or audience of the different types of music.[citation needed] For example, whereas the audience for Classical symphony concerts typically have above-average incomes, the audience for a rap concert in an inner-city area may have below-average incomes.[citation needed] Even though the performers, audience, or venue where non-"art" music is performed may have a lower socioeconomic status, the music that is performed, such as blues, rap, punk, funk, or ska may be very complex and sophisticated. When composers introduce styles of music that break with convention, there can be a strong resistance from academic music experts and popular culture. Late-period Beethoven string quartets, Stravinsky ballet scores, serialism, bebop-era jazz, hip hop, punk rock, and electronica have all been considered non-music by some critics when they were first introduced.[citation needed] Such themes are examined in the sociology of music. The sociological study of music, sometimes called sociomusicology, is often pursued in departments of sociology, media studies, or music, and is closely related to the field of ethnomusicology. Media and technology Further information: Computer music The music that composers make can be heard through several media; the most traditional way is to hear it live, in the presence of the musicians (or as one of the musicians), in an outdoor or indoor space such as an amphitheatre, concert hall, cabaret room or theatre. Live music can also be broadcast over the radio, television or the Internet. Some musical styles focus on producing a sound for a performance, while others focus on producing a recording that mixes together sounds that were never played "live." Recording, even of essentially live styles, often uses the ability to edit and splice to produce recordings considered better than the actual performance. As talking pictures emerged in the early 20th century, with their prerecorded musical tracks, an increasing number of moviehouse orchestra musicians found themselves out of work.[48] During the 1920s live musical performances by orchestras, pianists, and theater organists were common at first-run theaters.[49] With the coming of the talking motion pictures, those featured performances were largely eliminated. The American Federation of Musicians (AFM) took out newspaper advertisements protesting the replacement of live musicians with mechanical playing devices. One 1929 ad that appeared in the Pittsburgh Press features an image of a can labeled "Canned Music / Big Noise Brand / Guaranteed to Produce No Intellectual or Emotional Reaction Whatever"[50] Since legislation introduced to help protect performers, composers, publishers and producers, including the Audio Home Recording Act of 1992 in the United States, and the 1979 revised Berne Convention for the Protection of Literary and Artistic Works in the United Kingdom, recordings and live performances have also become more accessible through computers, devices and Internet in a form that is commonly known as Music-On-Demand. In many cultures, there is less distinction between performing and listening to music, since virtually everyone is involved in some sort of musical activity, often communal. In industrialized countries, listening to music through a recorded form, such as sound recording or watching a music video, became more common than experiencing live performance, roughly in the middle of the 20th century. Sometimes, live performances incorporate prerecorded sounds. For example, a disc jockey uses disc records for scratching, and some 20th-century works have a solo for an instrument or voice that is performed along with music that is prerecorded onto a tape. Computers and many keyboards can be programmed to produce and play Musical Instrument Digital Interface (MIDI) music. Audiences can also become performers by participating in karaoke, an activity of Japanese origin centered on a device that plays voice-eliminated versions of well-known songs. Most karaoke machines also have video screens that show lyrics to songs being performed; performers can follow the lyrics as they sing over the instrumental tracks. Internet The advent of the Internet has transformed the experience of music, partly through the increased ease of access to music and the increased choice. Chris Anderson, in his book The Long Tail: Why the Future of Business is Selling Less of More, suggests that while the economic model of supply and demand describes scarcity, the Internet retail model is based on abundance. Digital storage costs are low, so a company can afford to make its whole inventory available online, giving customers as much choice as possible. It has thus become economically viable to offer products that very few people are interested in. Consumers' growing awareness of their increased choice results in a closer association between listening tastes and social identity, and the creation of thousands of niche markets.[51] Another effect of the Internet arises with online communities like YouTube and Facebook, a social networking service. Such sites simplify connecting with other musicians, and greatly facilitate the distribution of music. Professional musicians also use YouTube as a free publisher of promotional material. YouTube users, for example, no longer only download and listen to MP3s, but also actively create their own. According to Don Tapscott and Anthony D. Williams, in their book Wikinomics, there has been a shift from a traditional consumer role to what they call a "prosumer" role, a consumer who both creates and consumes. Manifestations of this in music include the production of mashes, remixes, and music videos by fans.[52] Business Main article: Music industry The music industry refers to the business industry connected with the creation and sale of music. It consists of record companies, labels and publishers that distribute recorded music products internationally and that often control the rights to those products. Some music labels are "independent," while others are subsidiaries of larger corporate entities or international media groups. In the 2000s, the increasing popularity of listening to music as digital music files on MP3 players, iPods, or computers, and of trading music on file sharing sites or buying it online in the form of digital files had a major impact on the traditional music business. Many smaller independent CD stores went out of business as music buyers decreased their purchases of CDs, and many labels had lower CD sales. Some companies did well with the change to a digital format, though, such as Apple's iTunes, an online store that sells digital files of songs over the Internet. Education Non-professional Main article: Music education A Suzuki violin recital with students of varying ages. The incorporation of music training from preschool to post secondary education is common in North America and Europe. Involvement in music is thought to teach basic skills such as concentration, counting, listening, and cooperation while also promoting understanding of language, improving the ability to recall information, and creating an environment more conducive to learning in other areas.[53] In elementary schools, children often learn to play instruments such as the recorder, sing in small choirs, and learn about the history of Western art music. In secondary schools students may have the opportunity to perform some type of musical ensembles, such as choirs, marching bands, concert bands, jazz bands, or orchestras, and in some school systems, music classes may be available. Some students also take private music lessons with a teacher. Amateur musicians typically take lessons to learn musical rudiments and beginner- to intermediate-level musical techniques. At the university level, students in most arts and humanities programs can receive credit for taking music courses, which typically take the form of an overview course on the history of music, or a music appreciation course that focuses on listening to music and learning about different musical styles. In addition, most North American and European universities have some type of musical ensembles that non-music students are able to participate in, such as choirs, marching bands, concert bands, or orchestras. The study of Western art music is increasingly common outside of North America and Europe, such as the Indonesian Institute of the Arts in Yogyakarta, Indonesia, or the classical music programs that are available in Asian countries such as South Korea, Japan, and China. At the same time, Western universities and colleges are widening their curriculum to include music of non-Western cultures, such as the music of Africa or Bali (e.g. Gamelan music). Academia Musicology is the study of the subject of music. The earliest definitions defined three sub-disciplines: systematic musicology, historical musicology, and comparative musicology or ethnomusicology. In contemporary scholarship, one is more likely to encounter a division of the discipline into music theory, music history, and ethnomusicology. Research in musicology has often been enriched by cross-disciplinary work, for example in the field of psychoacoustics. The study of music of non-western cultures, and the cultural study of music, is called ethnomusicology. Students can pursue the undergraduate study of musicology, ethnomusicology, music history, and music theory through several different types of degrees, including a B.Mus, a B.A. with concentration in music, a B.A. with Honors in Music, or a B.A. in Music History and Literature. Graduates of undergraduate music programs can go on to further study in music graduate programs. Graduate degrees include the Master of Music, the Master of Arts, the Doctor of Philosophy (Ph.D.) (e.g., in musicology or music theory), and more recently, the Doctor of Musical Arts, or DMA. The Master of Music degree, which takes one to two years to complete, is typically awarded to students studying the performance of an instrument, education, voice or composition. The Master of Arts degree, which takes one to two years to complete and often requires a thesis, is typically awarded to students studying musicology, music history, or music theory. Undergraduate university degrees in music, including the Bachelor of Music, the Bachelor of Music Education, and the Bachelor of Arts (with a major in music) typically take three to five years to complete. These degrees provide students with a grounding in music theory and music history, and many students also study an instrument or learn singing technique as part of their program. The PhD, which is required for students who want to work as university professors in musicology, music history, or music theory, takes three to five years of study after the Master's degree, during which time the student will complete advanced courses and undertake research for a dissertation. The DMA is a relatively new degree that was created to provide a credential for professional performers or composers that want to work as university professors in musical performance or composition. The DMA takes three to five years after a Master's degree, and includes advanced courses, projects, and performances. In Medieval times, the study of music was one of the Quadrivium of the seven Liberal Arts and considered vital to higher learning. Within the quantitative Quadrivium, music, or more accurately harmonics, was the study of rational proportions. Zoomusicology is the study of the music of non-human animals, or the musical aspects of sounds produced by non-human animals. As George Herzog (1941) asked, "do animals have music?" François-Bernard Mâche's Musique, mythe, nature, ou les Dauphins d'Arion (1983), a study of "ornitho-musicology" using a technique of Nicolas Ruwet's Langage, musique, poésie (1972) paradigmatic segmentation analysis, shows that bird songs are organised according to a repetition-transformation principle. Jean-Jacques Nattiez (1990), argues that "in the last analysis, it is a human being who decides what is and is not musical, even when the sound is not of human origin. If we acknowledge that sound is not organised and conceptualised (that is, made to form music) merely by its producer, but by the mind that perceives it, then music is uniquely human." Music theory is the study of music, generally in a highly technical manner outside of other disciplines. More broadly it refers to any study of music, usually related in some form with compositional concerns, and may include mathematics, physics, and anthropology. What is most commonly taught in beginning music theory classes are guidelines to write in the style of the common practice period, or tonal music. Theory, even of music of the common practice period, may take many other forms. Musical set theory is the application of mathematical set theory to music, first applied to atonal music. Speculative music theory, contrasted with analytic music theory, is devoted to the analysis and synthesis of music materials, for example tuning systems, generally as preparation for composition. Ethnomusicology Main article: Ethnomusicology Ethnomusicologist Frances Densmore recording Blackfoot chief Mountain Chief for the Bureau of American Ethnology (1916) In the West, much of the history of music that is taught deals with the Western civilization's art music. The history of music in other cultures ("world music" or the field of "ethnomusicology") is also taught in Western universities. This includes the documented classical traditions of Asian countries outside the influence of Western Europe, as well as the folk or indigenous music of various other cultures. Popular styles of music varied widely from culture to culture, and from period to period. Different cultures emphasised different instruments, or techniques, or uses for music. Music has been used not only for entertainment, for ceremonies, and for practical and artistic communication, but also for propaganda. There is a host of music classifications, many of which are caught up in the argument over the definition of music. Among the largest of these is the division between classical music (or "art" music), and popular music (or commercial music – including rock music, country music, and pop music). Some genres do not fit neatly into one of these "big two" classifications, (such as folk music, world music, or jazz music). As world cultures have come into greater contact, their indigenous musical styles have often merged into new styles. For example, the United States bluegrass style contains elements from Anglo-Irish, Scottish, Irish, German and African instrumental and vocal traditions, which were able to fuse in the United States' multi-ethnic society. Genres of music are determined as much by tradition and presentation as by the actual music. Some works, like George Gershwin's Rhapsody in Blue, are claimed by both jazz and classical music, while Gershwin's Porgy and Bess and Leonard Bernstein's West Side Story are claimed by both opera and the Broadway musical tradition. Many current music festivals celebrate a particular musical genre. Indian music, for example, is one of the oldest and longest living types of music, and is still widely heard and performed in South Asia, as well as internationally (especially since the 1960s). Indian music has mainly three forms of classical music, Hindustani, Carnatic, and Dhrupad styles. It has also a large repertoire of styles, which involve only percussion music such as the talavadya performances famous in South India. Music therapy Main article: Music therapy Music therapy is an interpersonal process in which the therapist uses music and all of its facets—physical, emotional, mental, social, aesthetic, and spiritual—to help clients to improve or maintain their health. In some instances, the client's needs are addressed directly through music; in others they are addressed through the relationships that develop between the client and therapist. Music therapy is used with individuals of all ages and with a variety of conditions, including: psychiatric disorders, medical problems, physical handicaps, sensory impairments, developmental disabilities, substance abuse, communication disorders, interpersonal problems, and aging. It is also used to: improve learning, build self-esteem, reduce stress, support physical exercise, and facilitate a host of other health-related activities. One of the earliest mentions of music therapy was in Al-Farabi's (c. 872 – 950) treatise Meanings of the Intellect, which described the therapeutic effects of music on the soul.[54][verification needed] Music has long been used to help people deal with their emotions. In the 17th century, the scholar Robert Burton's The Anatomy of Melancholy argued that music and dance were critical in treating mental illness, especially melancholia.[55] He noted that music has an "excellent power ...to expel many other diseases" and he called it "a sovereign remedy against despair and melancholy." He pointed out that in Antiquity, Canus, a Rhodian fiddler, used music to "make a melancholy man merry, ...a lover more enamoured, a religious man more devout." [56][57][58] In November 2006, Dr. Michael J. Crawford[59] and his colleagues also found that music therapy helped schizophrenic patients.[60] In the Ottoman Empire, mental illnesses were treated with music.[61] Music Director............................. Music director From Wikipedia, the free encyclopedia A music director may be the director of an orchestra or concert band, the director of music for a film, the director of music at a radio station, the head of the music department in a school, the coordinator of the musical ensembles in a university, college, or institution[1] (but not usually the head of the academic music department), the head bandmaster of a military band, the head organist and choirmaster of a church, or an Organist and Master of the Choristers (a title given to a Director of Music at a cathedral, particularly in England). Contents [hide] 1 Orchestra 2 Film and theatre 3 Broadcasting 4 See also 5 References Orchestra[edit] The title of "music director" or "musical director" is used by many symphony orchestras to designate the primary conductor and artistic leader of the orchestra. The term "music director" is most common for orchestras in the United States. With European orchestras, the titles of "principal conductor" or "chief conductor" are more common, which designate the conductor who directs the majority of a given orchestra's concerts in a season. In musical theatre and opera, the music director is in charge of the overall musical performance, including ensuring that the cast knows the music thoroughly, supervising the musical interpretation of the performers and pit orchestra, and conducting the orchestra. In the 20th century, the title and position typically brought with it an almost unlimited influence over the particular orchestra's affairs. As implied by the name, the music director not only conducts concerts, but also controls what music the orchestra will perform or record, and has much authority regarding hiring, firing, and other personnel decisions over an orchestra's musicians. Such authoritarian rule, once expected and even thought necessary for a symphonic ensemble to function properly, has loosened somewhat in the closing decades of the 20th century with the advent and encouragement of more power sharing and cooperative management styles (with the orchestra musicians themselves, the administrative staff, and volunteer board of directors). The music director in American lingo also assists with fund-raising, and also is the primary focus of publicity for the orchestra, as what is often called its "public face".[2] The term "music director" or "musical director" became common in the United States in the middle of the 20th century, following an evolution of titles. Early leaders of orchestras were simply designated as the "conductor." In the 1920s and 1930s, the term musical director began to be used, in order to delineate the fact that the person in this position was doing much more than just conducting, and to differentiate them from guest conductors who simply led one particular program or concert. George Szell, for instance, was appointed as "musical director" of the Cleveland Orchestra in 1946, and his position was so named until his death in 1970. His successor, Lorin Maazel, was given the title "music director." Other major American orchestras kept more current with the times and began using the simpler term in the 1950s and '60s. The term can also refer to the person who directs a school band or heads the music program. Film and theatre[edit] Alternatively, the term "music director" used to appear in the film credits for a professional hired to supervise and direct the music selected for a film or music documentary, but today the more common designation is music supervisor. In India, where a large number of movies are produced as musicals, the term 'music director' is commonly used for the composer and music producer of the songs and score used in the film. Their roles also entail arranging, mastering, mixing and supervising recording of film music with conducting and orchestration. Usually, another artist will receive the credit for the lyrics of the songs. The "music director" for a theatrical production or Broadway or West End Musical often serves as rehearsal pianist and conductor. Brass bands, wind bands, choirs, opera companies and other ensembles may also have musical directors. Broadcasting[edit] A music director of a radio station is responsible for interacting with record company representatives, auditioning new music, and making decisions (sometimes in conjunction with the program director) as to which songs get airplay, how much and when. In college radio, there may be more than one music director, as students usually volunteer only a few hours each per week, and most stations have a diverse and extensive library of several different music genres. Musical Instruments................... A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be a musical instrument—it is through purpose that the object becomes a musical instrument. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 67,000 years. Some consensus dates early flutes to about 37,000 years ago. However, most historians believe that determining a specific time of musical instrument invention is impossible due to the subjectivity of the definition and the relative instability of materials used to make them. Many early musical instruments were made from animal skins, bone, wood, and other non-durable materials. Musical instruments developed independently in many populated regions of the world. However, contact among civilizations caused rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia were in Maritime Southeast Asia, and Europeans played instruments from North Africa. Development in the Americas occurred at a slower pace, but cultures of North, Central, and South America shared musical instruments. By 1400, musical instrument development slowed in many areas and was dominated by the Occident[citation needed]. Musical instrument classification is a discipline in its own right, and many systems of classification have been used over the years. Instruments can be classified by their effective range, their material composition, their size, etc. However, the most common academic method, Hornbostel-Sachs, uses the means by which they produce sound. The academic study of musical instruments is called organology.

Once humans moved from making sounds with their bodies—for example, by clapping—to using objects to create music from sounds, musical instruments were born.[1] Primitive instruments were probably designed to emulate natural sounds, and their purpose was ritual rather than entertainment.[citation needed] The concept of melody and the artistic pursuit of musical composition were unknown to early players of musical instruments.[dubious – discuss] A player sounding a flute to signal the start of a hunt does so without thought of the modern notion of "making music".[2] Musical instruments are constructed in a broad array of styles and shapes, using many different materials. Early musical instruments were made from "found objects" such a shells and plant parts.[2] As instruments evolved, so did the selection and quality of materials. Virtually every material in nature has been used by at least one culture to make musical instruments.[2] One plays a musical instrument by interacting with it in some way—for example, by plucking the strings on a string instrument. Archaeology[edit] Researchers have discovered archaeological evidence of musical instruments in many parts of the world. Some finds are 67,000 years old, however their status as musical instruments is often in dispute. Consensus solidifies about artifacts dated back to around 37,000 years old and later. Only artifacts made from durable materials or using durable methods tend to survive. As such, the specimens found cannot be irrefutably placed as the earliest musical instruments.[3] Found in Slovenia, the Divje Babe Flute is considered the world's oldest known musical instrument. In July 1995, Slovenian archaeologist Ivan Turk discovered a bone carving in the northwest region of Slovenia. The carving, named the Divje Babe Flute, features four holes that Canadian musicologist Bob Fink determined could have been used to play four notes of a diatonic scale. Researchers estimate the flute's age at between 43,400 and 67,000 years, making it the oldest known musical instrument and the only musical instrument associated with the Neanderthal culture.[4] However, some archaeologists and ethnomusicologists dispute the flute's status as a musical instrument.[5] German archaeologists have found mammoth bone and swan bone flutes dating back to 30,000 to 37,000 years old in the Swabian Alps. The flutes were made in the Upper Paleolithic age, and are more commonly accepted as being the oldest known musical instruments.[6] Archaeological evidence of musical instruments was discovered in excavations at the Royal Cemetery in the Sumerian city of Ur (see Lyres of Ur). These instruments, one of the first ensembles of instruments yet discovered, include nine lyres, two harps, a silver double flute, sistra and cymbals. A set of reed-sounded silver pipes discovered in Ur was the likely predecessor of modern bagpipes.[7] The cylindrical pipes feature three side-holes that allowed players to produce whole tone scales.[8] These excavations, carried out by Leonard Woolley in the 1920s, uncovered non-degradable fragments of instruments and the voids left by the degraded segments that, together, have been used to reconstruct them.[9] The graves these instruments were buried in have been carbon dated to between 2600 and 2500 BC, providing evidence that these instruments were used in Sumeria by this time.[10] Archaeologists in the Jiahu site of central Henan province of China have found flutes made of bones that date back 7,000 to 9,000 years,[11] representing some of the "earliest complete, playable, tightly-dated, multinote musical instruments" ever found.[11][12] History[edit] Scholars agree that there are no completely reliable methods of determining the exact chronology of musical instruments across cultures. Comparing and organizing instruments based on their complexity is misleading, since advancements in musical instruments have sometimes reduced complexity. For example, construction of early slit drums involved felling and hollowing out large trees; later slit drums were made by opening bamboo stalks, a much simpler task.[13] German musicologist Curt Sachs, one of the most prominent musicologists[14] and musical ethnologists[15] in modern times, argues that it is misleading to arrange the development of musical instruments by workmanship since cultures advance at different rates and have access to different raw materials. He maintains, for example, that contemporary anthropologists comparing musical instruments from two cultures that existed at the same time but differed in organization, culture, and handicraft cannot determine which instruments are more "primitive".[16] Ordering instruments by geography is also not totally reliable, as it cannot always be determined when and how cultures contacted one another and shared knowledge. Sachs proposed that a geographical chronology until approximately 1400 is preferable, however, due to its limited subjectivity.[17] Beyond 1400, one can follow the overall development of musical instruments by time period.[17] The science of marking the order of musical instrument development relies on archaeological artifacts, artistic depictions, and literary references. Since data in one research path can be inconclusive, all three paths provide a better historical picture.[3] Primitive and prehistoric[edit] Two Aztec slit drums, called teponaztli. The characteristic "H" slits can be seen on the top of the drum in the foreground Until the 19th century AD, European written music histories began with mythological accounts of how musical instruments were invented. Such accounts included Jubal, descendant of Cain and "father of all such as handle the harp and the organ", Pan, inventor of the pan pipes, and Mercury, who is said to have made a dried tortoise shell into the first lyre. Modern histories have replaced such mythology with anthropological speculation, occasionally informed by archeological evidence. Scholars agree that there was no definitive "invention" of the musical instrument since the definition of the term "musical instrument" is completely subjective to both the scholar and the would-be inventor. For example, a Homo habilis slapping his body could be the makings of a musical instrument regardless of the being's intent.[18] Among the first devices external to the human body that are considered instruments are rattles, stampers, and various drums.[19] These earliest instruments evolved due to the human motor impulse to add sound to emotional movements such as dancing.[20] Eventually, some cultures assigned ritual functions to their musical instruments, using them for hunting and various ceremonies.[21] Those cultures developed more complex percussion instruments and other instruments such as ribbon reeds, flutes, and trumpets. Some of these labels carry far different connotations from those used in modern day; early flutes and trumpets are so-labeled for their basic operation and function rather than any resemblance to modern instruments.[22] Among early cultures for whom drums developed ritual, even sacred importance are the Chukchi people of the Russian Far East, the indigenous people of Melanesia, and many cultures of Africa. In fact, drums were pervasive throughout every African culture.[23] One East African tribe, the Wahinda, believed it was so holy that seeing a drum would be fatal to any person other than the sultan.[24] Humans eventually developed the concept of using musical instruments for producing a melody. Until this time in the evolutions of musical instruments, melody was common only in singing. Similar to the process of reduplication in language, instrument players first developed repetition and then arrangement. An early form of melody was produced by pounding two stamping tubes of slightly different sizes—one tube would produce a "clear" sound and the other would answer with a "darker" sound. Such instrument pairs also included bullroarers, slit drums, shell trumpets, and skin drums. Cultures who used these instrument pairs associated genders with them; the "father" was the bigger or more energetic instrument, while the "mother" was the smaller or duller instrument. Musical instruments existed in this form for thousands of years before patterns of three or more tones would evolve in the form of the earliest xylophone.[25] Xylophones originated in the mainland and archipelago of Southeast Asia, eventually spreading to Africa, the Americas, and Europe.[26] Along with xylophones, which ranged from simple sets of three "leg bars" to carefully tuned sets of parallel bars, various cultures developed instruments such as the ground harp, ground zither, musical bow, and jaw harp.[27] Antiquity[edit] Images of musical instruments begin to appear in Mesopotamian artifacts in 2800 BC or earlier. Beginning around 2000 BC, Sumerian and Babylonian cultures began delineating two distinct classes of musical instruments due to division of labor and the evolving class system. Popular instruments, simple and playable by anyone, evolved differently from professional instruments whose development focused on effectiveness and skill.[28] Despite this development, very few musical instruments have been recovered in Mesopotamia. Scholars must rely on artifacts and cuneiform texts written in Sumerian or Akkadian to reconstruct the early history of musical instruments in Mesopotamia. Even the process of assigning names to these instruments is challenging since there is no clear distinction among various instruments and the words used to describe them.[29] Although Sumerian and Babylonian artists mainly depicted ceremonial instruments, historians have been able to distinguish six idiophones used in early Mesopotamia: concussion clubs, clappers, sistra, bells, cymbals, and rattles.[30] Sistra are depicted prominently in a great relief of Amenhotep III,[31] and are of particular interest because similar designs have been found in far-reaching places such as Tbilisi, Georgia and among the Native American Yaqui tribe.[32] The people of Mesopotamia preferred stringed instruments to any other, as evidenced by their proliferation in Mesopotamian figurines, plaques, and seals. Innumerable varieties of harps are depicted, as well as lyres and lutes, the forerunner of modern stringed instruments such as the violin.[33] Ancient Egyptian tomb painting depicting lute players, 18th Dynasty (c. 1350 BC). Musical instruments used by the Egyptian culture before 2700 BC bore striking similarity to those of Mesopotamia, leading historians to conclude that the civilizations must have been in contact with one another. Sachs notes that Egypt did not possess any instruments that the Sumerian culture did not also possess.[34] However, by 2700 BC the cultural contacts seem to have dissipated; the lyre, a prominent ceremonial instrument in Sumer, did not appear in Egypt for another 800 years.[34] Clappers and concussion sticks appear on Egyptian vases as early as 3000 BC. The civilization also made use of sistra, vertical flutes, double clarinets, arched and angular harps, and various drums.[35] Little history is available in the period between 2700 BC and 1500 BC, as Egypt (and indeed, Babylon) entered a long violent period of war and destruction. This period saw the Kassites destroy the Babylonian empire in Mesopotamia and the Hyksos destroy the Middle Kingdom of Egypt. When the Pharaohs of Egypt conquered Southwest Asia in around 1500 BC, the cultural ties to Mesopotamia were renewed and Egypt's musical instruments also reflected heavy influence from Asiatic cultures.[34] Under their new cultural influences, the people of the New Kingdom began using oboes, trumpets, lyres, lutes, castanets, and cymbals.[36] In contrast with Mesopotamia and Egypt, professional musicians did not exist in Israel between 2000 and 1000 BC. While the history of musical instruments in Mesopotamia and Egypt relies on artistic representations, the culture in Israel produced few such representations. Scholars must therefore rely on information gleaned from the Bible and the Talmud.[37] The Hebrew texts mention two prominent instruments associated with Jubal, ugabs and kinnors. These may be translated as pan pipes and lyres, respectively.[38] Other instruments of the period included tofs, or frame drums, small bells or jingles called pa'amon, shofars, and the trumpet-like hasosra.[39] The introduction of a monarchy in Israel during the 11th century BC produced the first professional musicians and with them a drastic increase in the number and variety of musical instruments.[40] However, identifying and classifying the instruments remains a challenge due to the lack of artistic interpretations. For example, stringed instruments of uncertain design called nevals and asors existed, but neither archaeology nor etymology can clearly define them.[41] In her book A Survey of Musical Instruments, American musicologist Sibyl Marcuse proposes that the nevel must be similar to vertical harp due to its relation to "nabla", the Phoenician term for "harp".[42] In Greece, Rome, and Etruria, the use and development of musical instruments stood in stark contrast to those cultures' achievements in architecture and sculpture. The instruments of the time were simple and virtually all of them were imported from other cultures.[43] Lyres were the principal instrument, as musicians used them to honor the gods.[44] Greeks played a variety of wind instruments they classified as aulos (reeds) or syrinx (flutes); Greek writing from that time reflects a serious study of reed production and playing technique.[8] Romans played reed instruments named tibia featuring side-holes that could be opened or closed, allowing for greater flexibility in playing modes.[45] Other instruments in common use in the region included vertical harps derived from those of the Orient, lutes of Egyptian design, various pipes and organs, and clappers, which were played primarily by women.[46] Evidence of musical instruments in use by early civilizations of India is almost completely lacking, making it impossible to reliably attribute instruments to the Munda and Dravidian language-speaking cultures that first settled the area. Rather, the history of musical instruments in the area begins with the Indus Valley Civilization that emerged around 3000 BC. Various rattles and whistles found among excavated artifacts are the only physical evidence of musical instruments.[47] A clay statuette indicates the use of drums, and examination of the Indus script has also revealed representations of vertical arched harps identical in design to those depicted in Sumerian artifacts. This discovery is among many indications that the Indus Valley and Sumerian cultures maintained cultural contact. Subsequent developments in musical instruments in India occurred with the Rigveda, or hymns. These songs used various drums, shell trumpets, harps, and flutes.[48] Other prominent instruments in use during the early centuries AD were the snake charmer's double clarinet, bagpipes, barrel drums, cross flutes, and short lutes. In all, India had no unique musical instruments until the Middle Ages.[49] A Chinese wooden fish, used in Buddhist recitations Musical instruments such as zithers appeared in Chinese writings around 12th century BC and earlier.[50] Early Chinese philosophers such as Confucius (551–479 BC), Mencius (372–289 BC), and Laozi shaped the development of musical instruments in China, adopting an attitude toward music similar to that of the Greeks. The Chinese believed that music was an essential part of character and community, and developed a unique system of classifying their musical instruments according to their material makeup.[51] Idiophones were extremely important in Chinese music, hence the majority of early instruments were idiophones. Poetry of the Shang Dynasty mentions bells, chimes, drums, and globular flutes carved from bone, the latter of which has been excavated and preserved by archaeologists.[52] The Zhou Dynasty saw percussion instruments such as clappers, troughs, wooden fish, and yu. Wind instruments such as flute, pan-pipes, pitch-pipes, and mouth organs also appeared in this time period.[53] The xiao and various other instruments that spread through many cultures, came into use in China during and after the Han Dynasty.[54] Although civilizations in Central America attained a relatively high level of sophistication by the eleventh century AD, they lagged behind other civilizations in the development of musical instruments. For example, they had no stringed instruments; all of their instruments were idiophones, drums, and wind instruments such as flutes and trumpets. Of these, only the flute was capable of producing a melody.[55] In contrast, pre-Columbian South American civilizations in areas such as modern-day Peru, Colombia, Ecuador, Bolivia, and Chile were less advanced culturally but more advanced musically. South American cultures of the time used pan-pipes as well as varieties of flutes, idiophones, drums, and shell or wood trumpets.[56] Middle Ages[edit] During the period of time loosely referred to as the Middle Ages, China developed a tradition of integrating musical influence from other regions. The first record of this type of influence is in 384 AD, when China established an orchestra in its imperial court after a conquest in Turkestan. Influences from Middle East, Persia, India, Mongolia, and other countries followed. In fact, Chinese tradition attributes many musical instruments from this period to those regions and countries.[57] Cymbals gained popularity, along with more advanced trumpets, clarinets, oboes, flutes, drums, and lutes.[58] Some of the first bowed-zithers appeared in China in the 9th or 10th century, influenced by Mongolian culture.[59] India experienced similar development to China in the Middle Ages; however, stringed instruments developed differently as they accommodated different styles of music. While stringed instruments of China were designed to produce precise tones capable of matching the tones of chimes, stringed instruments of India were considerably more flexible. This flexibility suited the slides and tremolos of Hindu music. Rhythm was of paramount importance in Indian music of the time, as evidenced by the frequent depiction of drums in reliefs dating to the Middle Ages. The emphasis on rhythm is an aspect native to Indian music.[60] Historians divide the development of musical instruments in medieval India between pre-Islamic and Islamic periods due to the different influence each period provided.[61] In pre-Islamic times, idiophones such hand bells, cymbals, and peculiar instruments resembling gongs came into wide use in Hindu music. The gong-like instrument was a bronze disk that was struck with a hammer instead of a mallet. Tubular drums, stick zithers named veena, short fiddles, double and triple flutes, coiled trumpets, and curved India horns emerged in this time period.[62] Islamic influences brought new types of drums, perfectly circular or octagonal as opposed to the irregular pre-Islamic drums.[63] Persian influence brought oboes and sitars, although Persian sitars had three strings and Indian version had from four to seven.[64] An Indonesian metallophone. Southeast Asian musical innovations include those during a period of Indian influence that ended around 920 AD.[65] Balinese and Javanese music made use of xylophones and metallophones, bronze versions of the former.[66] The most prominent and important musical instrument of Southeast Asia was the gong. While the gong likely originated in the geographical area between Tibet and Burma, it was part of every category of human activity in Maritime Southeast Asia including Java.[67] The areas of Mesopotamia and the Arabian Peninsula experiences rapid growth and sharing of musical instruments once they were united by Islamic culture in the seventh century.[68] Frame drums and cylindrical drums of various depths were immensely important in all genres of music.[69] Conical oboes were involved in the music that accompanied wedding and circumcision ceremonies. Persian miniatures provide information on the development of kettle drums in Mesopotamia that spread as far as Java.[70] Various lutes, zithers, dulcimers, and harps spread as far as Madagascar to the south and modern-day Sulawesi to the east.[71] Despite the influences of Greece and Rome, most musical instruments in Europe during the Middles Ages came from Asia. The lyre is the only musical instrument that may have been invented in Europe until this period.[72] Stringed instruments were prominent in Middle Age Europe. The central and northern regions used mainly lutes, stringed instruments with necks, while the southern region used lyres, which featured a two-armed body and a crossbar.[72] Various harps served Central and Northern Europe as far north as Ireland, where the harp eventually became a national symbol.[73] Lyres propagated through the same areas, as far east as Estonia.[74] European music between 800 and 1100 became more sophisticated, more frequently requiring instruments capable of polyphony. The Persian geographer of the 9th century (Ibn Khordadbeh), mentioned in his lexicographical discussion of music instruments that in the Byzantine Empire typical instruments included the urghun (organ), shilyani (probably a type of harp or lyre), salandj (probably a bagpipe) and the Byzantine lyra (Greek: λύρα ~ lūrā).[75] Lyra was a medieval pear-shaped bowed string instrument with three to five strings, held upright and is an ancestor of most European bowed instruments, including the violin.[76] The monochord served as a precise measure of the notes of a musical scale, allowing more accurate musical arrangements.[77] Mechanical hurdy-gurdies allowed single musicians to play more complicated arrangements than a fiddle would; both were prominent folk instruments in the Middle Ages.[78][79] Southern Europeans played short and long lutes whose pegs extended to the sides, unlike the rear-facing pegs of Central and Northern European instruments.[80] Idiophones such as bells and clappers served various practical purposes, such as warning of the approach of a leper.[81] The ninth century revealed the first bagpipes, which spread throughout Europe and had many uses from folk instruments to military instruments.[82] The construction of pneumatic organs evolved in Europe starting in fifth century Spain, spreading to England in about 700.[83] The resulting instruments varied in size and use from portable organs worn around the neck to large pipe organs.[84] Literary accounts of organs being played in English Benedictine abbeys toward the end of the tenth century are the first references to organs being connected to churches.[85] Reed players of the Middle Ages were limited to oboes; no evidence of clarinets exists during this period.[86] Modern[edit] Renaissance[edit] Musical instrument development was dominated by the Occident from 1400 on, indeed, the most profound changes occurred during the Renaissance period.[18] Instruments took on other purposes than accompanying singing or dance, and performers used them as solo instruments. Keyboards and lutes developed as polyphonic instruments, and composers arranged increasingly complex pieces using more advanced tablature. Composers also began designing pieces of music for specific instruments.[18] In the latter half of the sixteenth century, orchestration came into common practice as a method of writing music for a variety of instruments. Composers now specified orchestration where individual performers once applied their own discretion.[87] The polyphonic style dominated popular music, and the instrument makers responded accordingly.[88] The Duet, by Dutch painter Cornelis Saftleven, c. 1635 Beginning in about 1400, the rate of development of musical instruments increased in earnest as compositions demanded more dynamic sounds. People also began writing books about creating, playing, and cataloging musical instruments; the first such book was Sebastian Virdung's 1511 treatise Musica getuscht und ausgezogen (English: Music Germanized and Abstracted).[87] Virdung's work is noted as being particularly thorough for including descriptions of "irregular" instruments such as hunters' horns and cow bells, though Virdung is critical of the same. Other books followed, including Arnolt Schlick's Spiegel der Orgelmacher und Organisten (English: Mirror of Organ Makers and Organ Players) the following year, a treatise on organ building and organ playing.[89] Of the instructional books and references published in the Renaissance era, one is noted for its detailed description and depiction of all wind and stringed instruments, including their relative sizes. This book, the Syntagma musicum by Michael Praetorius, is now considered an authoritative reference of sixteenth century musical instruments.[90] In the sixteenth century, musical instrument builders gave most instruments, such as the violin, the "classical shapes" they retain today. An emphasis on aesthetic beauty also developed—listeners were as pleased with the physical appearance of an instrument as they were with its sound. Therefore, builders paid special attention to materials and workmanship, and instruments became collectibles in homes and museums.[91] It was during this period that makers began constructing instruments of the same type in various sizes to meet the demand of consorts, or ensembles playing works written for these groups of instruments.[92] Instrument builders developed other features that endure today. For example, while organs with multiple keyboards and pedals already existed, the first organs with solo stops emerged in the early fifteenth century. These stops were meant to produce a mixture of timbres, a development needed for the complexity of music of the time.[93] Trumpets evolved into their modern form to improve portability, and players used mutes to properly blend into chamber music.[94] Baroque[edit] Baroque mounted Jacob Stainer violin from 1658 Beginning in the seventeenth century, composers began creating works of a more emotional style. They felt that a monophonic style better suited the emotional music and wrote musical parts for instruments that would complement the singing human voice.[88] As a result, many instruments that were incapable of larger ranges and dynamics, and therefore were seen as unemotional, fell out of favor. One such instrument was the shawm.[95] Bowed instruments such as the violin, viola, baryton, and various lutes dominated popular music.[96] Beginning in around 1750, however, the lute disappeared from musical compositions in favor of the rising popularity of the guitar.[97] As the prevalence of string orchestras rose, wind instruments such as the flute, oboe, and bassoon were readmitted to counteract the monotony of hearing only strings.[98] In the mid-seventeenth century, what was known as a hunter's horn underwent transformation into an "art instrument" consisting of a lengthened tube, a narrower bore, a wider bell, and much wider range. The details of this transformation are unclear, but the modern horn or, more colloquially, French horn, had emerged by 1725.[99] The slide trumpet appeared, a variation that includes a long-throated mouthpiece that slid in and out, allowing the player infinite adjustments in pitch. This variation on the trumpet was unpopular due to the difficulty involved in playing it.[100] Organs underwent tonal changes in the Baroque period, as manufacturers such as Abraham Jordan of London made the stops more expressive and added devices such as expressive pedals. Sachs viewed this trend as a "degeneration" of the general organ sound.[101] Classical and Romantic[edit] During the Classical and Romantic periods of music, lasting from roughly 1750 to 1900, a great deal of musical instruments capable of producing new timbres and higher volume were developed and introduced into popular music. The design changes that broadened the quality of timbres allowed instruments to produce a wider variety of expression. Large orchestras rose in popularity and, in parallel, the composers determined to produce entire orchestral scores that made use of the expressive abilities of modern instruments. Since instruments were involved in collaborations of a much larger scale, their designs had to evolve to accommodate the demands of the orchestra.[102] Some instruments also had to become louder to fill larger halls and be heard over sizable orchestras. Flutes and bowed instruments underwent many modifications and design changes—most of them unsuccessful—in efforts to increase volume. Other instruments were changed just so they could play their parts in the scores. Trumpets traditionally had a "defective" range—they were incapable of producing certain notes with precision.[103] New instruments such as the clarinet, saxophone, and tuba became fixtures in orchestras. Instruments such as the clarinet also grew into entire "families" of instruments capable of different ranges: small clarinets, normal clarinets, bass clarinets, and so on.[102] Accompanying the changes to timbre and volume was a shift in the typical pitch used to tune instruments. Instruments meant to play together, as in an orchestra, must be tuned to the same standard lest they produce audibly different sounds while playing the same notes. Beginning in 1762, the average concert pitch began rising from a low of 377 vibrations to a high of 457 in 1880 Vienna.[104] Different regions, countries, and even instrument manufacturers preferred different standards, making orchestral collaboration a challenge. Despite even the efforts of two organized international summits attended by noted composers like Hector Berlioz, no standard could be agreed upon.[105] Twentieth century to present[edit] Headstock of a Fender Stratocaster electric guitar The evolution of traditional musical instruments slowed beginning in the twentieth century.[106] Instruments like the violin, flute, french horn, harp, and so on are largely the same as those manufactured throughout the eighteenth and nineteenth centuries. Gradual iterations do emerge; for example, the "New Violin Family" began in 1964 to provide differently sized violins to expand the range of available sounds.[107] The slowdown in development was practical response to the concurrent slowdown in orchestra and venue size.[108] Despite this trend in traditional instruments, the development of new musical instruments exploded in the twentieth century. The sheer variety of instruments developed overshadows any prior period.[106] The proliferation of electricity in the twentieth century lead to the creation of an entirely new category of musical instruments: electronic instruments, or electrophones.[109] The vast majority of electrophones produced in the first half of the twentieth century were what Sachs called "electromechanical instruments". In other words, they have mechanical parts that produce sound vibrations, and those vibrations are picked up and amplified by electrical components. Examples of electromechanical instruments include organs and electric guitars.[109] Sachs also defined a subcategory of "radioelectric instruments" such as the theremin, which produces music through the player's hand movements around two antennas.[110] The latter half of the twentieth century saw the gradual evolution of synthesizers—instruments that artificially produce sound using analog or digital circuits and microchips. In the late 1960s, Bob Moog and other inventors began an era of development of commercial synthesizers. One of the first of these instruments was the Moog synthesizer.[111] The modern proliferation of computers and microchips has spawned an entire industry around electronic musical instruments. Since electronic musical instruments may produce sound without human interaction, there is debate in the modern music community as to whether or not computer musicians may be considered instrumentalists.[citation needed] Classification[edit] Main article: Musical instrument classification There are many different methods of classifying musical instruments. Various methods examine aspects such as the physical properties of the instrument (material, color, shape, etc.), the use for the instrument, the means by which music is produced with the instrument, the range of the instrument, and the instrument's place in an orchestra or other ensemble. Most methods are specific to a geographic area or cultural group and were developed to serve the unique classification requirements of the group.[112] The problem with these specialized classification schemes is that they tend to break down once they are applied outside of their original area. For example, a system based on instrument use would fail if a culture invented a new use for the same instrument. Scholars recognize Hornbostel-Sachs as the only system that applies to any culture and, more important, provides only possible classification for each instrument.[113][114] Ancient systems[edit] An ancient system named the Natya Shastra, written by the sage Bharata Muni and dating from between 200 BC and 200 AD, divides instruments into four main classification groups: instruments where the sound is produced by vibrating strings; percussion instruments with skin heads; instruments where the sound is produced by vibrating columns of air; and "solid", or non-skin, percussion instruments.[113] This system was adapted to some degree in 12th-century Europe by Johannes de Muris, who used the terms tensibilia (stringed instruments), inflatibilia (wind instruments), and percussibilia (all percussion instruments).[115] In 1880, Victor-Charles Mahillon adapted the Natya Shastra and assigned Greek labels to the four classifications: chordophones (stringed instruments), membranophones (skin-head percussion instruments), aerophones (wind instruments), and autophones (non-skin percussion instruments).[113] Hornbostel-Sachs[edit] Erich von Hornbostel and Curt Sachs adopted Mahillon's scheme and published an extensive new scheme for classification in Zeitschrift für Ethnologie in 1914. Hornbostel and Sachs used most of Mahillon's system, but replaced the term autophone with idiophone.[113] The original Hornbostel-Sachs system classified instruments into four main groups: Idiophones, which produce sound by vibrating the primary body of the instrument itself; they are sorted into concussion, percussion, shaken, scraped, split, and plucked idiophones, such as claves, xylophone, guiro, slit drum, mbira, and rattle.[116] Membranophones, which produce sound by a vibrating a stretched membrane; they may be drums (further sorted by the shape of the shell), which are struck by hand, with a stick, or rubbed, but kazoos and other instruments that use a stretched membrane for the primary sound (not simply to modify sound produced in another way) are also considered membranophones.[117] Chordophones, which produce sound by vibrating one or more strings; they are sorted into according to the relationship between the string(s) and the sounding board or chamber. For example, if the strings are laid out parallel to the sounding board and there is no neck, the instrument is a zither whether it is plucked like an autoharp or struck with hammers like a piano. If the instrument has strings parallel to the sounding board or chamber and the strings extend past the board with a neck, then the instrument is a lute, whether the sound chamber is constructed of wood like a guitar or uses a membrane like a banjo.[118] Aerophones, which produce a sound by with a vibrating column of air; they are sorted into free aerophones such as a bullroarer or whip, which move freely through the air; flutes, which cause the air to pass over a sharp edge; reed instruments, which use a vibrating reed; and lip-vibrated aerophones such as trumpets, for which the lips themselves function as vibrating reeds.[119] Sachs later added a fifth category, electrophones, such as theremins, which produce sound by electronic means.[109] Within each category are many subgroups. The system has been criticised and revised over the years, but remains widely used by ethnomusicologists and organologists.[115][120] Schaeffner[edit] Andre Schaeffner, a curator at the Musée de l'Homme, disagreed with the Hornbostel-Sachs system and developed his own system in 1932. Schaeffner believed that the pure physics of a musical instrument, rather than its specific construction or playing method, should always determine its classification. (Hornbostel-Sachs, for example, divide aerophones on the basis of sound production, but membranophones on the basis of the shape of the instrument). His system divided instruments into two categories: instruments with solid, vibrating bodies and instruments containing vibrating air.[121] Range[edit] Main article: Instrument range Musical instruments are also often classified by their musical range in comparison with other instruments in the same family. This exercise is useful when placing instruments in context of an orchestra or other ensemble. These terms are named after singing voice classifications: Soprano instruments: flute, violin, soprano saxophone, trumpet, clarinet, oboe, piccolo Alto instruments: alto saxophone, french horn, english horn, viola, alto horn Tenor instruments: trombone, tenor saxophone, guitar, tenor drum Baritone instruments: bassoon, baritone saxophone, bass clarinet, cello, baritone horn, euphonium Bass instruments: double bass, bass guitar, bass saxophone, tuba, bass drum Some instruments fall into more than one category: for example, the cello may be considered tenor, baritone or bass, depending on how its music fits into the ensemble, and the trombone may be alto, tenor, baritone, or bass and the French horn, bass, baritone, tenor, or alto, depending on the range it is played in. Many instruments have their range as part of their name: soprano saxophone, tenor saxophone, baritone horn, alto flute, bass guitar, etc. Additional adjectives describe instruments above the soprano range or below the bass, for example: sopranino saxophone, contrabass clarinet. When used in the name of an instrument, these terms are relative, describing the instrument's range in comparison to other instruments of its family and not in comparison to the human voice range or instruments of other families. For example, a bass flute's range is from C3 to F♯6, while a bass clarinet plays about one octave lower. Construction[edit] The materials used in making musical instruments vary greatly by culture and application. Many of the materials have special significance owing to their source or rarity. Some cultures worked substances from the human body into their instruments. In ancient Mexico, for example, the material drums were made from might contain actual human body parts obtained from sacrificial offerings. In New Guinea, drum makers would mix human blood into the adhesive used to attach the membrane.[122] Mulberry trees are held in high regard in China owing to their mythological significance—instrument makers would hence use them to make zithers. The Yakuts believe that making drums from trees struck by lightning gives them a special connection to nature.[123] Musical instrument construction is a specialized trade that requires years of training, practice, and sometimes an apprenticeship. Most makers of musical instruments specialize in one genre of instruments; for example, a luthier makes only stringed instruments. Some make only one type of instrument such as a piano. Whatever the instrument constructed, the instrument maker must consider materials, construction technique, and decoration, creating a balanced instrument that is both functional and aesthetically pleasing.[124] Some builders are focused on a more artistic approach and develop experimental musical instruments, often meant for individual playing styles developed by the builder himself. User interfaces[edit] Regardless of how the sound in an instrument is produced, many musical instruments have a keyboard as the user-interface. Keyboard instruments are any instruments that are played with a musical keyboard. Every key generates one or more sounds; most keyboard instruments have extra means (pedals for a piano, stops for an organ) to manipulate these sounds. They may produce sound by wind being fanned (organ) or pumped (accordion),[125][126] vibrating strings either hammered (piano) or plucked (harpsichord),[127][128] by electronic means (synthesizer),[129] or in some other way. Sometimes, instruments that do not usually have a keyboard, such as the glockenspiel, are fitted with one.[130] Though they have no moving parts and are struck by mallets held in the player's hands, they have the same physical arrangement of keys and produce soundwaves in a similar manner.
