The Choir's raison d'etre has, since its inception, been to sing services in the College Chapel. Choral Evensong is sung twice weekly during Full Term. More generally, the Choir makes an important contribution to the life of the College, singing at feasts, weddings, memorial services and other occasions.

Today, as one of Cambridge's finest mixed-voice ensembles, the group also pursues an exciting range of activities outside College, performing concerts in Cambridge and around the UK, recording CDs, broadcasting, and undertaking major international tours each  Summer. Choir members are selected by audition either before or after coming up to Cambridge, and each is expected to be of a very high musical standard. Most hold Choral Exhibitions, and all benefit from regular vocal training.
