A composer is a person who writes music, including the melodies for singing and instruments. They may specialize in a particular style of music, such as classical, jazz, or music for film and TV. Composers may work alone or as part of a team, and they may have assistants who help them with tasks such as editing recorded audio or notating passages. The term "composer" is often used to denote people who are composers by occupation, or those who work in the tradition of Western classical music, but it can refer to any person who writes music. In contrast, a songwriter is a composer who specializes in writing songs, often with lyrics.
