The Holden Choirs are three choral ensembles at Harvard University, consisting of the Harvard Glee Club, the Radcliffe Choral Society, and the Harvard-Radcliffe Collegium Musicum (respectively a men's, a women's, and a mixed chorus.) Each year the three Holden Choirs combine to perform a large choral-orchestral work. When they do so, they are referred to as "The Holden Chorus." The Harvard-Radcliffe Chorus is an adjunct member, consisting of both Harvard students and members of the broader community, and serving in part as a training chorus for the other groups.
