The refrain of a song, repeated a number of times, in alternation with verses and other sections (e.g. a guitar solo). In contrast to the verses of a song, the chorus tends to be simpler and more memorable, and it often uses more repetition of lyrics (e.g. “She loves you yeah, yeah, yeah…”). The term “chorus” may also be a synonym for “choir”—a group of singers; or it may refer to a chorus effect—the sound created when a voice or instrumental tone is doubled by other pitches which are not exactly the same, which creates a rich, shimmering sound.
