The Choir of Clare College, Cambridge, is a mixed-voice choir whose primary function is to lead services in Clare College's chapel at the University of Cambridge in Cambridge, England. Since the founding of the choir in 1971, the Choir of Clare College has gained an international reputation as one of the leading university choral groups in the world. 　　The first chapel choir was formed in 1866. For the next one hundred years the choir consisted of undergraduate lower voices and a treble line provided by boys from city schools. In 1966, the use of boys was discontinued and for a brief period there was no upper line. The current mixed-voice choir was established in 1971 by Peter Dennison, a music fellow of the college. He was succeeded by the college's first director of music, John Rutter. Rutter left in 1979 to focus on composing but retains a close connection with the college as an honorary fellow. Timothy Brown directed the choir for 31 years until he was succeeded by the choir's current director of music, Graham Ross.
