I've been obsessed with the clavichord recently. So much so that I've been reading up on how to build one, ha ha! I don't really have the resources to build one or buy one at the moment though. But I've been making a ton of baroque (and modern) style improvs on my digital piano using the "clavichord" sound. Yes, the "bebung" effect is one of the many reasons why I am interested in the instrument. I wonder why they never placed a mechanism into the piano that allowed this effect. It seems like you could put a lever beneath the keys, so when you hold down a key you could make a note have a vibrato or a bend.
