Double-manual, Pedal Clavichord after J.D. Gerstenberg, ca. 1760, is actually three separate instruments stacked one on top of the other and played like an organ. The two manual instruments, each with two 8' choirs, are of slightly different case depths. The lowest instrument, deeper in tone, slides out from an enclosure to simulate an organ's lower manual. The largest of the three instruments, upon which the manual clavichords rest, features 8' and 16' choirs and is operated by a pedal keyboard. The entire ensemble of clavichords is well-suited for the trio sonatas of Bach, as well as other organ music of 17th-and 18th-centuries.
