Columbia University's esteemed Collegium Musicum is a classical music a cappella choir that specializes in sacred and secular vocal music from the medieval, Renaissance, and contemporary repertoires. Collegium Musicum incorporates vocal and instrumental performance practice techniques, improvisation, and gesture in bold, imaginative concerts inspired by historical performance practice. The Collegium Musicum is one of Columbia University's leading choral ensembles and has been a part of University life since the mid-1950s. The group is connected to Columbia's core curriculum, traditionally singing Josquin's Ave Maria...virgo serena for Music Humanities classes. Although in the past the Collegium has devoted itself to the performance of music of the middle ages and Renaissance -- that by composers like Machaut, Josquin, Palestrina, Ockeghem, Tallis, and Monteverdi -- in recent years the Collegium has broadened its repertoire to embrace works of all historical epochs, including 20th-century and contemporary music.
The 2019-2020 director of Collegium Musicum is PhD student Russell O'Rourke, and rehearsals are held Mondays from 7:30-9:30 pm.
