Composer

A composer is a person who writes music. The term is especially used to indicate composers of Western classical music, or those who are composers by occupation. Many composers are, or were, also skilled performers of music.

The term is descended from Latin, compōnō; literally "one who puts together". The earliest use of the term in a musical context given by the Oxford English Dictionary is from Thomas Morley's 1597 A Plain and Easy Introduction to Practical Music, where he says "Some wil [sic] be good descanters [...] and yet wil be but bad composers".

"Composer" is a loose term that generally refers to any person who writes music. More specifically, it is often used to denote people who are composers by occupation, or those who work in the tradition of Western classical music. Writers of exclusively or primarily songs may be called composers, but since the 20th century the terms 'songwriter' or 'singer-songwriter' are more often used, particularly in popular music genres. In other contexts, the term 'composer' can refer to a literary writer, or more rarely and generally, someone who combines pieces into a whole.

Across cultures and traditions composers may write and transmit music in a variety of ways. In much popular music, the composer writes a composition, and it is then transmitted via oral tradition. Conversely, in some Western classical traditions music may be composed aurally—i.e. "in the mind of the musician"—and subsequently written and passed through written documents.

In the development of European classical music, the function of composing music initially did not have much greater importance than that of performing it.^{[citation needed]} The preservation of individual compositions did not receive enormous attention and musicians generally had no qualms about modifying compositions for performance.

In the Western world, before the Romantic period of the 19th century, composition almost always went side by side with a combination of either singing, instructing and theorizing.

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 their 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 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.
