This is a version of Bach’s first movement from the Well Tempered Clavier, the Praeludium. I absolutely love the version of this on the piano by Sviatoslav Richter, where he plays it so softly and perfectly.
This version uses finger piano samples, taken from an instrument I built back in 1978 or so. I’ve been using the samples for almost 10 years for all kinds of music. I carefully filed down a dob of solder that I applied to the tips of the spring steel blades so that the overtone is exactly two octaves higher than the fundamental. Without the solder, the overtone is enharmonic. I accidentally discovered that I could tune the overtone when I added solder just to get the pitch lower in a smaller space. The fact that I could tune it was a bonus I would have never known was possible. It was only by fiddling around with a small steel file and a soldering iron for untold hours in the basement room B-160 in Mandeville Center at U.C.S.D. that I made the discovery.
