Theme music
Theme music is a piece that is often written specifically for a radio program, television program, video game or movie, and usually played during the intro, during title sequence and/or ending credits. If it is accompanied by lyrics, most often associated with the show, it is a
theme song. When the theme song is named for the title of the work, it is the
title song. The phrase
theme song or
signature tune may also be used to refer to a signature song that has become especially associated with a particular performer or dignitary; often used as they make an entrance. The purpose of a theme song is often similar to that of a leitmotif.
