Terpistone - The Music of Dance

Leon Theremin is most well-known for the invention that carries his name.  A theremin is a musical instrument which is played by waving your hands in the air around it.  The movements are quite a bit more sophisticated than that but the key point is that there is no actual contact with a string or anything of that nature.  (Wiki:  Theremin)

Theremin also considered what else might control music and that's when he invented the Terpistone, a larger version of the Theremin.  A dancer in front of a Terpistone moves up and down to control the pitch and then forward and back to control the volume.  (Theremin.Info:  Leon Theremin's Musical Dance Platform)

Only one example of the Terpistone still exists but that's not such a tragedy.  Theremin was building these devices in the 20's and 30's or so.  The electronics he had at his disposal were ridiculously primitive relative to what is available today so making another one shouldn't be a huge feat.  There are theremins for sale all over eBay, the electronics just couldn't be that tough.

The only question is why would you bother to make a Terpistone today.  So imagine three or four dancers on a stage all, in effect, jamming with each other through the movements of their bodies.  If you're clever enough with your electronics, one or more of these devices could also be used to control lights.

So, find yourself an E.E. (Electrical Engineer) as there are probably lots of them since so much electronic production was cleverly shipped overseas.  Get cracking on this project and let's see what it looks like.  I know some dancers in the Knoxville area who would make something like this shoot sparks at the Moon so, yah, let's see this device in production.
