The music The first 6 tracks are the Gavotte in A minor with Variations by Jean-Phillipe Rameau. Tracks 7-12 are the English Suite #3 in Gminor by Johann Sebastian Bach. Tracks 13-14 are J.S. Bach, Prelude and Fugue in G# minor. Tracks 15-17 are L. Sarason, Piano Sonata (1948). The movements are labeled 1) Allegro Moderato, 2) Scherzo and 3) Slow and Espressivo. Some sidelights The harpsichord used was electo-accoustic. It is now extinct, so it might be labeled an historical instrument. It had no soundboard just an amplifier and filters. Mechanical damping of the bridge simulated the radiation resistance and frictional losses of the soundboard. Leonard Sarason (1925-1998) obtained his doctorate in Composition at Yale. His advisor was Paul Hindemith. After a doctorate in Mathematics at NYU he taught mathematics at Stanford and the University of Washington.
