A composer (Latin compōnō; literally "one who puts together") is a person who writes music, especially classical music[1] 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.

Classical composer Mozart

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