"TONEWHEELS is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions.

In this three day workshop from 24-27 October 2009, participants built a simple light-to-sound converter and DC motor controller, and then began to experiment with drawing sounds onto transparent "tonewheels". The workshop ended in a group performance and an invitation to the audience to try out the instruments for themselves.

As you can see, both the participants and the audience had a great time with this. I did too! My thanks go to Galina Dimitrova, Rene Beekman, Prof. Svetoslav Kokalov, Venelin Shurelov, DA Festival, National Academy of the Arts Sofia, Elena Kaludova and all the participants for a fantastic workshop in Bulgaria!"

"TONEWHEELS is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions. Transparent tonewheels with repeating patterns are spun over light-sensitive electronic circuitry to produce sound and light pulsations and textures. This all-analog set is performed entirely live without the use of computers, using only overhead projectors as light source, performance interface and audience display. In this way, TONEWHEELS aims to open up the "black box" of electronic music and video by exposing the working processes of the performance for the audience to see.

"First TONEWHEELS performance, August 25 2007 at the "Kunst & Musik mit dem Tageslichtprojektor" workshop, Molkerei Gallery Cologne, DE. Yes, I do bite the electronics and get a mouthful of 12V DC at the end!
