The Choir is made up of 24 Choristers and Probationers from St John’s College School, and 15 Choral Scholars who are members of St John’s College, and its primary purpose is to enhance the liturgy and worship at daily services in the College Chapel. The Choir is renowned for championing contemporary music in its commissioning of new works, including recent compositions by the College’s first Composer in Residence Michael Finnissy, Nico Muhly and James Burton.
The Choir brings the 'St John's Sound' to listeners around the world through its weekly webcasts. In May 2016 the College launched its new ‘St John’s Cambridge’ label (in conjunction with Signum Records) on which the Choir has released the critically acclaimed and BBC Music Magazine Award winning recording of Jonathan Harvey’s music, Jonathan Harvey: Deo, Christmas with St John's, Kyrie, and Mass in G minor in May 2018. The Choir also maintains a busy schedule of concerts events, and tours abroad.
