Keyboard arrangements of Mozart’s compositions, ranging from one of his earliest minuets to his tribute to J.S. Bach, reveal the variety and fecundity of his imagination, not least in the inspired collection made by the great pianist Edwin Fischer, and in the excerpts from the playful Londoner Skizzenbuch. They are performed on two original and newly restored instruments, the Tangentenflügel—a transitional keyboard instrument with a unique tone quality that sounds like a harpsichord endowed with dynamics—and the pantalon square piano. This is the first recording ever made of a historical pantalon.
