Our live is audio-visual. There are other senses involved – touch, smell, temperature sensation, but here I want to focus on seeing and listening simultaneously. Film is the prime focus of this inquiry; this is why Michel Chion called one of his books Audio-Vision (1994).
When we go to a concert, seeing the musicians performing, gesturing, creating energy, working through a score – this is as important for understanding the music as listening to the musical tones.
Ryoji Ikeda pushes the concept of audio-vision further by generating both sound and images (he is not the only one: Carsten Nicolai and Alva Noto (some people have more than one identiy), Ryoichi Kurokawa, ….and others).
Programmes like processing, MAX/MSP, pd, SuperCollider and enable new audio-visual art practices.
But nothing is new. Oscar Fischinger, Hans Richter, Walter Ruttmann, Len Lye experimented audio-visually. The Centre for Visual Music does what the name says.
