Music

Music is an art form that involves what are sometimes organised sounds and silence, although in some forms of 20th century aleatoric, and indeed improvisational music, as well as most Eastern traditions such as Gamelou, this is not the case. It is expressed in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture).

Music may also involve generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, ceremonial or religious purposes and by many composers purely as an academic instrument for study.

The definition of what constitutes music varies according to culture and social context, with varied interpretations of the term being accepted under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.


The history of music predates the written word and is tied to the development of each unique human culture. The development of music among humans occurred against the backdrop of natural sounds such as birdsong and the sounds other animals use to communicate. Prehistoric music, once more commonly called primitive music, is the name given to all music produced in preliterate cultures (prehistory), beginning somewhere in very late geological history.

Ancient music
The earliest records of musical expression are to be found in the Sama Veda of India and in 4,000 year old cuneiform from Ur. Instruments, such as the seven holed flute and various types of stringed instruments have been recovered from the Indus valley civilization archaeological sites. [3] The Indian music is one of the oldest musical traditions in the world, and Indian classical music (marga) can be found from the scriptures of the Hindu tradition, the Vedas. Chinese classical music, the traditional art or court music of China has a history stretching for more than three thousand years. Music was an important part of cultural and social life in Ancient Greece. In ancient Greece, mixed-gender choruses performed for entertainment, celebration and spiritual ceremonies, and musicians and singers had an important role in Greek theater. Music was part of children's basic education in ancient Greece.


Medieval and Renaissance music
While musical life was undoubtedly rich in the early Medieval era, as attested by artistic depictions of instruments, writings about music, and other records, the only repertory of music which has survived from before 800 to the present day is the plainsong liturgical music of the Roman Catholic Church, the largest part of which is called Gregorian chant. Several schools of polyphony flourished in the period after 1100. Alongside these schools of sacred music a vibrant tradition of secular song developed, as exemplified in the music of the troubadours, trouvères and Minnesänger.

Much of the surviving music of the 14th century in European music history is secular. By the middle of the 15th century, composers and singers used a smooth polyphony for sacred musical compositions such as the mass, the motet, and the laude; and secular forms such as the chanson and the madrigal. The invention of printing had an immense influence on the dissemination of musical styles.


Baroque music
Main article: Baroque music
The first operas, written around 1600 and the rise of Counterpoint musical compositions define the end of the Renaissance and the beginning of the Baroque era that lasted until 1750, the year of the death of J.S. Bach, today the most generally known of the Baroque composers (though many composers embraced the Baroque movement in music during those years).

German Baroque composers wrote for small ensembles including strings, brass, and woodwinds, as well as Choirs, pipe organ, harpsichord, and clavichord. During the Baroque 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.[1]

Classical music
Main article: Classical music
The music of the Classical period is characterised by homophonic texture, often featuring prominent melody with accompaniment. These new melodies tended to be almost voice-like and singable. The now popular instrumental music was dominated by further evolution of musical forms initially defined in the Baroque period: the sonata, and the concerto, with the addition of the new form, the symphony. Wolfgang Amadeus Mozart, well known even today, is among the central figures of the Classical period.


Romantic music
Main article: Romantic music
Ludwig van Beethoven and Franz Schubert were transitional composers, leading into the Romantic period, with their expansion of existing genres, forms, and functions of music. In the Romantic period, music became more expressive and emotional, expanding to encompass literature, art, and philosophy. 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. Later Romantic composers created complex and often much longer musical works, merging and expanding traditional forms that had previously been used separately. For example, counterpoint, combined with harmonic structures to create more extended chords with increased use of dissonance and to create dramatic tension and resolution.


Impressionist music
Main article: Impressionist music
The impressionist movement in music is a movement in European classical music that had its beginnings in the late nineteenth century and continued into the middle of the twentieth century. Musical Impressionism focused on suggestion and atmosphere rather than strong emotion or the depiction of a story. Impressionist composers favored short forms such as the nocturne, arabesque, and prelude, and the use of unresolved dissonance and uncommon scales such as the whole tone scale. Musical Impressionism was based in France, and the French composers Claude Debussy and Maurice Ravel are generally considered to be two of the most well-known Impressionists.


20th Century music
Main article: 20th century music
The 20th Century saw a revolution in music listening as the radio gained popularity worldwide and new media and technologies were developed to record, capture, reproduce and distribute music. 20th Century music brought a new freedom and wide experimentation with new musical styles and forms that challenged the accepted rules of music of earlier periods, including both new popular forms as well as evolution of new classical forms such as Twelve-tone technique.


Music in the West
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 in totalitarian countries.

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 and roll, country music, and pop music). Some genres don't 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. While most classical music is acoustic and meant to be performed by individuals or groups, many works described as "classical" include samples or tape, or are mechanical. Some works, like Gershwin's Rhapsody in Blue, are claimed by both jazz and classical music. Many current music festivals celebrate a particular musical genre.


Production
Main article: Music industry
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 attempt to 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. As well, professional musicians work as freelancers, seeking contracts and engagements in a variety of settings.

Although amateur musicians differ from professional musicians in that amateur musicians have a non-musical source of income, 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 and orchestras. In some rare 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).


Performance
Main article: Performance

Chinese Nakhi musiciansPerformance is the execution of music. While music cannot technically exist without performance, we generally think of performance as being the exhibition of a musical work before an audience. A musical work is performed once its structure and instrumentation are satisfactory to its creators; however, as it gets performed more and more over time, it can evolve and change in any number of ways.

A performance can either be rehearsed or improvised. Improvisation is a musical idea created on the spot, with no prior premeditation, while rehearsal is vigorous repetition of an idea until it has achieved cohesion. Musicians will generally add improvisation to a well-rehearsed idea to create a unique performance.


Solo and ensemble performances
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. A performer may be referred to as a musician.


Aural tradition

Musical notationMany types of music, such as traditional blues and folk 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 which demand improvisation or modification to the music. In the Gambia, West Africa, the history of the country is passed aurally through song.


Music notation
Main article: Musical notation
When music is written down, the pitches and rhythm of the music is notated, along with instructions on how to perform the music. This is referred to as musical notation, and 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. Nonetheless, 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, 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 for the performers to read from. To perform music from notation requires an understanding of both the musical style and the performance practice that is associated with a piece of music or genre.


Ornamentation
The detail included explicitly in the music notation varies between genres and historical periods. In general, art music notation from the 17th through to 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, unornamented melody. However, it was expected that performers would 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. It was expected that the performer would 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.


Improvisation, interpretation, composition
Main articles: Musical composition, Musical improvisation, and Free improvisation
Most 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, where as interpretation is generally used to mean either individual choices of a performer, or an aspect of music which 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. According to the analysis of Georgiana Costescu, improvised music usually follows stylistic or genre conventions and even "fully composed" includes some freely chosen material (see precompositional). 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" which may create musical sounds, examples of this range from wind chimes, through computer programs which select sounds. Music which contains elements selected by chance is called Aleatoric music, and is often associated with John Cage, Witold Lutosławski, and Steve Reich.


Composition
Musical composition is a term that describes the composition of a piece of music. Methods of composition vary widely from one composer to another, however in analysing music all forms -- spontaneous, trained, or untrained -- are built from elements comprising a musical piece. 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.

What is important in understanding the composition of a piece is singling out its elements. An understanding of music's formal elements can be helpful in deciphering exactly how a piece is constructed. A universal element of music is how sounds occur in time, which is referred to as the rhythm of a piece of music.

When a piece appears to have a changing time-feel, it is considered to be in rubato time, an Italian expression that indicates that the tempo of the piece changes to suit the expressive intent of the performer. Even random placement of random sounds, which occurs in musical montage, occurs within some kind of time, and thus employs time as a musical element.


Reception and audition
Main article: Hearing (sense)
Further information: psychoacoustics

Concert in the Mozarteum, SalzburgThe field of music cognition involves the study of many aspects of music including how it is processed by listeners. Deaf people can experience music by feeling the vibrations in their body, a process which can be enhanced if the individual holds a resonant, hollow object. A well-known deaf musician is the composer Ludwig van Beethoven, who composed many famous works even after he had completely lost his hearing. Recent examples of deaf musicians include Evelyn Glennie, a highly acclaimed percussionist who has been deaf since the age of twelve, and Chris Buck, a virtuoso violinist who has lost his hearing.

Music is experienced by individuals in a range of social settings ranging from being alone to attending a large concert. 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.

On the other hand, other types of music such as 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 socioeconomic 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 hip-hop concert in an inner-city area may have below-average incomes. 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, hip-hop, punk, funk, or ska may be very complex and sophisticated.

When composers introduce styles of music which 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]


Media and Technology
The music that composers make can be heard through several media; the most traditional way is to hear it live, in the presence, or as one of the musicians. 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 which mixes together sounds which were never played "live". Recording, even of styles which are essentially live, often uses the ability to edit and splice to produce recordings which are 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.[2] During the 1920s live musical performances by orchestras, pianists, and theater organists were common at first-run theaters[3] With the coming of the talking motion pictures, those featured performances were largely eliminated. The American Federation of Musicians 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" [4]

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, as virtually everyone is involved in some sort of musical activity, often communal. In industrialised 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 DJ 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 MIDI music. Audiences can also become performers by participating in Karaoke, an activity of Japanese origin which centres around 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.


Education
Professional musicians in some cultures and musical genres compose, perform, and improvise music with no formal training. Musical genres where professional musicians are typically self-taught or where they learn through informal mentoring and creative exchanges include folk, blues, punk, and popular music genres such as rock and pop.

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.

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 PhD (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.

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 Doctor of Musical Arts (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.


Music as Part of General Education
Main article: Music education
The incorporation of music training from preschool to postsecondary education is common in North America and Europe, because 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 conductive to learning in other areas. [5] 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 an 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, or orchestras. The study of Western art music is increasingly common outside of North America and Europe, such as STSI in Bali, 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).


Study
Main articles: musicology and music theory
Many people also study about music in the field of musicology. The earliest definitions of musicology defined three sub-disciplines: systematic musicology, historical musicology, and comparative musicology. 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.

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 Ruwet's Language, musique, poésie (1972) paradigmatic segmentation analysis, shows that birdsongs 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 that which studies 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.


Use in therapy
Robert Burton wrote in the 16th century in his classic work, The Anatomy of Melancholy, that music and dance were critical in treating mental illness, especially melancholia. [6] He said that "But to leave all declamatory speeches in praise of divine music, I will confine myself to my proper subject: besides that excellent power it hath to expel many other diseases, it is a sovereign remedy against despair and melancholy, and will drive away the devil himself." Burton noted that "...Canus, a Rhodian fiddler, in Philostratus, when Apollonius was inquisitive to know what he could do with his pipe, told him, "That he would make a melancholy man merry, and him that was merry much merrier than before, a lover more enamoured, a religious man more devout.

In November 2006, Dr. Michael J. Crawford [10] and his colleagues also found that music therapy helped schizophrenic patients. [11] In Ottoman Empire, mental illnesses were treated with music.
