The organist and composer Christian Michael Wolff spent most of his life in Stettin (now Szczecin, Poland) as a highly respected musician. Among his surviving works is a collection of six sonatas for a melody instrument and obbligato harpsichord, from which this Sonata in C major for viola or viola da gamba (bass or tenor viol) and harpsichord or harp is taken. With this edition, we present a work that expands the not very extensive early Classical repertoire for this instrumentarium, and particularly that for the tenor viol.
