Catherine Bott talks to harpsichordist Gary Cooper about the role of the continuo, from its early beginnings around the turn of the 17th century, up to vocal and instrumental music by JS Bach. They discuss the use of different instruments as part of the continuo ensemble, including a simple organ in very early examples, and the use of chitarrone in Monteverdi, and viola da gamba in Rameau. Catherine and Gary also talk about the impact the continuo makes to a musical performance. Repertoire in the programme includes works by Viadana, Monteverdi, Frescobaldi and JS Bach.
