Music is an art form and cultural activity whose medium is sound organized in time. The common elements of music are pitch (which governs melody and harmony ), rhythm (and its associated concepts tempo , meter , and articulation ), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of
instruments and vocal techniques ranging from singing to rapping ; there are solely
instrumental pieces , solely vocal pieces (such as songs without instrumental
accompaniment ) and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike ; "art of the In its most general form, the activities describing music as an art form or cultural activity include the creation of works of music (songs, tunes, symphonies , and so on), the
criticism of music, the study of the history of music, and the aesthetic examination of music. 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." [2]
The creation, performance, significance, and even the definition of music vary according to culture and social context. Indeed, throughout history, some new forms or styles of music have been criticized as "not being music", including Beethoven 's Grosse Fuge string quartet in 1825, [3] early jazz in the beginning of the 1900s[4] and hardcore punk in the 1980s.[5] There are many types of music, including popular music, traditional music, art music, music written for religious ceremonies and work songs such as chanteys. Music ranges from strictly organized compositions–such as Classical music symphonies from the 1700s and 1800s, through to spontaneously played improvisational music such as jazz , and avant-garde styles of chance-based
contemporary music from the 20th and 21st centuries.
Music can be divided into genres (e.g.,
country music) and genres can be further divided into subgenres (e.g., country blues and pop country are two of the many country subgenres), although the dividing lines and relationships between music genres are often subtle, sometimes open to personal interpretation, and occasionally controversial. For example, it can be hard to draw the line between some early 1980s hard rock and
heavy metal . Within the arts, music may be classified as a performing art, a fine art or as an auditory art. Music may be played or sung and heard live at a rock concert or orchestra performance, heard live as part of a dramatic work (a music theater show or opera), or it may be recorded and listened to on a radio, MP3 player, CD player, smartphone or as film score or TV show.
In many cultures, music is an important part of people's way of life, as it plays a key role in religious rituals , rite of passage ceremonies (e.g., graduation and marriage), social activities (e.g., dancing ) and cultural activities ranging from amateur karaoke singing to playing in an amateur funk band or singing in a community choir . People may make music as a hobby, like a teen playing cello in a youth orchestra , or work as a professional musician or singer. The music industry includes the individuals who create new songs and musical pieces (such as songwriters and composers), individuals who perform music (which include orchestra, jazz band and rock band musicians, singers and conductors), individuals who record music (music producers and sound engineers ), individuals who organize concert tours, and individuals who sell recordings and sheet music and scores to customers. Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy the sheet music of their favourite pieces and songs so that they could perform them at home on the piano. With the advent of sound recording, records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs. With the advent of home tape recorders in the 1980s and digital music in the 1990s, music lovers could make tapes or
playlists of their favourite songs and take them with them on a portable cassette player or MP3 player. Some music lovers create mix tapes of their favorite songs, which serve as a "self-portrait, a gesture of friendship, prescription for an ideal party... [and] an environment consisting solely of what is most ardently loved." [7]
Amateur musicians can compose or perform music for their own pleasure, and derive their income elsewhere. Professional musicians are employed by a range of institutions and organisations, including armed forces (in
marching bands , concert bands and popular music groups), churches and synagogues, symphony orchestras, broadcasting or film production companies, and music schools. Professional musicians sometimes work as freelancers or session musicians , 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 community
concert bands and community orchestras.
A distinction is often made between music performed for a live audience and music that is performed in a studio so that it can be 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 also recorded and distributed. Live concert recordings are popular in both classical music and in popular music forms such as rock, where illegally taped live concerts are prized by music lovers. In the jam band scene, live, improvised jam sessions are preferred to studio recordings. In the 2000s, music notation typically means the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music, such as the notes of a melody , are notated. Music notation also often provides instructions on how to perform the music. For example, the sheet music for a song may state that the song is a "slow blues" or a "fast swing", which indicates the tempo and the genre. To read music notation, a person must have an understanding of music theory,
harmony and the performance practice associated with a particular song or piece's genre.
Written notation varies with style and period of music. In the 2000s, notated music is produced as sheet music or, for individuals with computer scorewriter programs, as an image on a computer screen . In ancient times, music notation was put onto stone or clay tablets. To perform music from notation, a singer or instrumentalist requires an understanding of 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 genres requiring musical improvisation , the performer often plays from music where only the chord changes and form of the song are written, requiring the performer to have a great understanding of the music's structure, harmony and the styles of a particular genre (e.g., jazz or country 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. Fake books are also used in jazz; they may consist of lead sheets or simply chord charts, which permit rhythm section members to improvise an accompaniment part to jazz songs. 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.
