French composer Louis-Nicolas Clérambault composing at the keyboard

A composer (Latin compōnō; literally "one who puts together") is a musician who is an author of music in any form, including vocal music (for a singer or choir), instrumental music, electronic music, and music which combines multiple forms. A composer may create music in any music genre, including, for example, classical music, musical theatre, blues, folk music, jazz, and popular music. Composers often express their works in a written musical score using musical notation.

Many composers are, or were, also skilled performers of music.

Composers and performers

Musical notation serves as a set of directions for a performer, but there is a whole continuum of possibilities concerning how much the performer determines the final form of the rendered work in performance.

Even in a conventional Western piece of instrumental music, in which all of the melodies, chords, and basslines are written out in musical notation, the performer has a degree of latitude to add artistic interpretation to the work, by such means as by varying his or her articulation and phrasing, choosing how long to make fermatas (held notes) or pauses, and — in the case of bowed string instruments, woodwinds or brass instruments — deciding whether to use expressive effects such as vibrato or portamento. For a singer or instrumental performer, the process of deciding how to perform music that has been previously composed and notated is termed "interpretation". Different performers' interpretations of the same work of music can vary widely, in terms of the tempos that are chosen and the playing or singing style or phrasing of the melodies. Composers and songwriters who present their own music are interpreting, just as much as those who perform the music of others. 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 the individual choices of a performer.[citation needed]

Although a musical composition often has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when a band collaborates to write a song, or in musical theatre, where the songs may be written by one person, the orchestration of the accompaniment parts and writing of the overture is done by an orchestrator, and the words may be written by a third person.

A piece of music can also be composed with words, images, or, in the 20th and 21st century, computer programs that explain or notate how the singer or musician should create musical sounds. Examples of this range from wind chimes jingling in a breeze, to avant-garde music from the 20th century that uses graphic notation, to text compositions such as Aus den sieben Tagen, to computer programs that select sounds for musical pieces. Music that makes heavy use of randomness and chance is called aleatoric music, and is associated with contemporary composers active in the 20th century, such as John Cage, Morton Feldman, and Witold Lutosławski.

The nature and means of individual variation of the music is varied, depending on the musical culture in the country and time period it was written. For instance, music composed in the Baroque era, particularly in slow tempos, often was written in bare outline, with the expectation that the performer would add improvised ornaments to the melody line during a performance. Such freedom generally diminished in later eras, correlating with the increased use by composers of more detailed scoring in the form of dynamics, articulation et cetera; composers becoming uniformly more explicit in how they wished their music to be interpreted, although how strictly and minutely these are dictated varies from one composer to another. Because of this trend of composers becoming increasingly specific and detailed in their instructions to the performer, a culture eventually developed whereby faithfulness to the composer's written intention came to be highly valued (see, for example, Urtext edition). This musical culture is almost certainly related to the high esteem (bordering on veneration) in which the leading classical composers are often held by performers.

The historically informed performance movement has revived to some extent the possibility of the performer elaborating in a serious way the music as given in the score, particularly for Baroque music and music from the early Classical period. The movement might be considered a way of creating greater faithfulness to the original in works composed at a time that expected performers to improvise. In genres other than classical music, the performer generally has more freedom; thus for instance when a performer of Western popular music creates a "cover" of an earlier song, there is little expectation of exact rendition of the original; nor is exact faithfulness necessarily highly valued (with the possible exception of "note-for-note" transcriptions of famous guitar solos).

In Western art music, the composer typically orchestrates his or her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a pop songwriter may not use notation at all, and instead compose the song in his or her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music. The 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 the creation of popular and traditional music songs and instrumental pieces and to include spontaneously improvised works like those of free jazz performers and African percussionists such as Ewe drummers.
