Tonewheels is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions. We previewed Tonewheels a few months ago.
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.
