Rafaël Rozendaal has a new website viralling. Fallingfalling uses the same Shepard Tone I remember using in the legendary 1980s Seattle stage production of “Rocky Jones and the Space P.O.L.K.A. Patrol in Ride, Ride My Rocket”. Developed by Roger Shepard at Bell Labs, the tone was also featured in a Scientific American article by Diana Deutsch. I had to use a phonograph recording of the Shepard Tone, you can get the digital or CD version at the links below.
