A choir (/ Ë k w aÉª. Ér /) (also known as a quire, chorale or chorus) is a musical ensemble of singers. Choral music, in turn, is the music written specifically for such an ensemble to perform. Choirs may perform music from the classical music repertoire, which spans from the Medieval era to the present, or popular music repertoire.
Chorus is often used in a theatrical context, such as opera or musical theater, for the group of singers (and often dancers) who back up the featured performers. Chorale can refer to a particular type of church music, or simply be another name for a choir or chorus.
