Hetti started becoming interested in early music whilst a student at Birmingham Conservatoire. It was the actual instruments which captured her imagination, which has led her to learn and collect various types of cello and viol, including the baroque and classical cellos, the arpeggione (one of the only ones currently in the UK), the treble, tenor and bass viols, the violone, and the bass violin, the later of which is the subject of her PhD research. Her interest in instruments led her to found the ‘8ft project’, taking various different types of cello and viols from all periods in history to schools, music colleges, festivals and exhibitions across the UK, giving talks about their role and use across the world.
Hetti regularly performs with ‘Florisma’ and the viol consort ‘Birds on Fire’, and has recorded CD’s for commercial release with various early music groups, including Florisma, The Birmingham Baroque Collective, Lady Georgianna, Eboracum Baroque, the Apollo Consort, The Amade Players, and The Brook Street Band. She performs extensively across the UK and Europe as a continuo player on both the baroque cello and viola da gamba.
