The sonatas for viola da gamba and harpsichord were almost certainly composed at Leipzig during the last 20 years of Bach's life. In modern times they are usually offered as a set, both in print and in recording, merely because of their instrumentation. But they were conceived independently from one another, perhaps for the Leipzig Collegium Musicum performances Bach conducted between 1729 and 1741 at Zimmerman's Coffee House. This concert series was a major focus of Bach's musical life in the 1730's. The scores originate between 1736 and 1741, a period when Bach was deeply involved in chamber music. These sonatas are a graphic representation of Bach's philosophy, not just of music, but of the purpose of life. Bach saw the world as created, ordered and logical. His art reflected his cooperation in this system and he apprehended learned counterpoint as the preeminent brush for painting the natural world through music. In his mind it is counterpoint, two or more melodies moving together, that create vertical relationships - harmony, and spatial relationships - rhythm. The sonatas recorded here present three, distinct voices between trombone and the keyboardist's right and left hands. These voices moving together exemplify much more than the demonstration of Bach's mastery of musical construction; he was not interested in purely abstract goals. He sought to prove the existence of God, to relate truth, to represent the natural order of the world. Knitting the melodies together in this way create an aesthetic reality only implied by any single voice, a reality that exists and merely awaits discovery through counterpoint. Indeed, Bach expressed the depths of his faith through learned counterpoint and it is the Mass in B Minor and Art of Fugue that arguably represent his most profound compositions. The gamba sonatas are incidental by comparison but the astounding craft and creativity in them demonstrate the depths at which Bach integrates theory with practice. They present real problems for the trombonist. Chief among them are extended phrase lengths and the continuous nature of Bach's counterpoint. Rest is precious to brass players and little is afforded here. Extended range is also a great challenge to the trombonist as is the dexterity required in fast movements and ornamentation. But the majestic sound of the trombone imbues this great music with the spirit of a mighty steed.

This recording is the second in a long-term program of research that contributes solutions, new techniques, and suggestions of melodic embellishment to trombone repertoire of the Baroque era. The first, Arcangelo Corelli Solo Chamber Sonatas Opus 5, was released in 2004. Mike Hall is a C.G. Conn and Selmer Bach performing artist.
