Editor's reconstruction of the third movement of a lost Bach chamber work, from a "work-complex" that includes movements from J. S. Bach's Sonata in G Major for Viola da Gamba and Obbligato Harpsichord (BWV 1027) and the Sonata in G Major for Two Flutes and Continuo (BWV 1039). Intended as the companion to nos. 1–3 in this volume.
