About us

INDEX CANTORUM is unashamedly a ‘list of singers’ who, on occasion, take a break from professional commitments, musical or otherwise, to sing purely for pleasure. The repertoire that the group performs spans several centuries, and includes familiar favourites and lesser-known pieces, often specially edited from original sources.  Founded in 1988, INDEX CANTORUM started with a concert in the London Church of St Paul’s Covent Garden. More recently INDEX CANTORUM has performed in Winchester, giving concerts in St Lawrence Church, St Pauls Church, and singing in the Cathedral for Evensong and Compline.  Other cathedral engagements have been Choral Vespers marking the King Alfred 1100 anniversary, and a gala concert as part of the Winchester celebration of the 450th anniversary of the marriage of Philip II of Spain to Mary Tudor, and lunchtime recitals.  INDEX CANTORUM has also sung services in Salisbury and Chichester.
