Rhytmicon
I was delighted to finally find a video of this device in action. I’ve been fascinated by it for some time, because it was really one of the first “rhythm machines” ever made. It’s very interesting to think that such radical sound machines were already being made and played in 30’s. The Rhythmicon was commissioned by composer Henry Cowell and built by Theramin. Now if I could get my hands on a performance of the “Rhythmicana (Concerto for Rhythmicon and Orchestra; 1931)”, that would would be nice.
