A cantata is a vocal composition with an instrumental accompaniment, typically in several movements, often involving a choir.

A choir is a musical ensemble of singers. Choral music, in turn, is the music written specifically for such an ensemble to perform or in other words is the music performed by the ensemble. Choirs may perform music from the classical music repertoire, which spans from the medieval era to the present, or popular music repertoire. Most choirs are led by a conductor, who leads the performances with arm, hand, and facial gestures.
