A film composer writes music for movies. Your duties can also include creating original compositions for television shows and other types of productions. As a composer, your responsibilities involve writing music that fits with each scene in a movie. The director and producer expect composers to evoke the appropriate mood to match what happens in the film. After you write the score for a production, you work with musicians, arrangers, and music producers to record it. You direct musicians and artists during each recording session. Composers may also produce a compilation of pieces from the movie for a soundtrack album.
