Bach, JS - Trio Sonata No. 5 in C, BWV 529 (arr)  Ref: 3--002 Arranged for violin (or flute) and viola, with cello, keyboard or both. One of a set of six trio sonatas for the organ which are among Bach's major works for the instrument. This arrangement is designed for maximum versatility.  The optional keyboard part was written with the harpsichord in mind, or a synthesizer with a harpsichord stop, but it will also work well with a chamber organ. see sample score
