Choir

A choir (/ˈkwaɪ.ər/) (also known as a 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, and/or popular music repertoire. Most choirs are led by a conductor, who leads the performances with arm and face gestures.
