About us

IINDEX CANTORUM is a well-established chamber choir that delights in combining its Early Music specialism with a wide range of familiar and newly commissioned works, creating imaginative performances built around distinctive and original themes. Founded in 1988, the choir gave its first concerts in London at St Paul’s, Covent Garden, and St Patrick’s, Soho Square. Since then, INDEX CANTORUM has become a regular presence in Winchester, singing Evensong and Compline services in the Cathedral and performing in its popular lunchtime concert series. The choir has also appeared at Salisbury and Chichester Cathedrals, as well as in venues across Hampshire, including regular concerts in East Meon, Bishop’s Sutton, and St Cross.

INDEX CANTORUM has collaborated with instrumental ensembles such as Les Haulz et le Bas and Simply Baroque. Notable performances include a tour of the Scottish Highlands in 2017, and concerts for the Stockbridge Music series and Le Manoir aux Quat’Saisons Christmas Carol series in 2018. In 2026 INDEX CANTORUM undertook its first foreign tour to Valencia.
