January 10th 2009 2PM+: Tonewheels--drawn sound and light music with
Derek Holzer

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

In this workshop, participants will learn about different optoelectronic
components (photodiodes, photoresistors, phototransistors and
photoelectric cells) and how they can be used to create sound from
natural or electronic light sources in our everyday world, as well as
from lasers and other modulated light sources. Circuits to drive motors
in order to create hand-drawn spinning "tonewheels" will also be shown.

About the instructor:

Derek Holzer [USA 1972] is a sound artist who has performed live
audiovisual sets using laptops and the Pure Data programming language
since 2001. Becoming frustrated with the performance limitations of the
computer, he began new experiments with all-analog, light-driven systems
in the summer of 2007 which led to the TONEWHEELS live performance.
Since then, TONEWHEELS has been performed in Germany, the Netherlands,
Sweden, Italy, Estonia, Poland and Belgium.

Workshop fee: 12 euros.



Workshops led by field-expert practitioners extend over realms of code
and embedded code, environmental code, noise, transmission and
reception, and electromysticism. Workshops solely utilise free
software and GNU toolbase.
