composer

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.
