the case bottom, normally the structural foundation of a
Viennese fortepiano, to be eliminated, enhancing sound
projection not only to the audience but also to any
players behind the fortepiano, where an open lid normally
creates an acoustical shadow;
the action, bridge, and soundboard design to be
the characteristic touch and tone color of earlier Viennese
fortepianos to be retained.
Our extended compass 6 1/2-octave fortepiano was designed
1999 after studying, handling, and in some cases repairing several fortepianos by Graf, c. 1830 and later, and one of the earliest instruments built with a Bösendorfer label, c. 1828.
