Three regular services are sung per week in full University Term, and the choir sings Latin grace from the minstrels' gallery in the college's Great Hall at a number of feasts.
The constitution of the medieval chapel choir remains obscure, but the choral foundation which Mary Tudor established in 1553 (ten choristers, six lay clerks, four priests, an organist, and a schoolmaster) survived essentially unchanged for over 300 years.
The choir has toured to destinations such as Australia, Germany, France, Spain, Italy, the United States, Canada, the Canary Islands, India, South Africa, Namibia and Zimbabwe, Peru, and Japan, Taiwan and Hong Kong.
The choir also performs concerts in the UK, at home in Cambridge and in London (South Bank Centre, St John's Smith Square, Spitalfields Festival), and around the country.
‘Livings tours’ allow the choir to visit parishes around the country of which the college is patron and sing services and concerts; these include villages in the Isle of Wight, North Yorkshire, County Durham, Norfolk and the Lake District.
