Our intention is to affirm this life, not to bring order out of chaos, nor to suggest improvements in creation, but simply to wake up to the very lif… - John Cage

Wherever we are, what we hear is mostly noise. When we ignore it, it disturbs us. When we listen to it, we find it fascinating. The sound of a truck at fifty miles per hour. Static between the stations. Rain. We want to capture and control these sounds, to use them not as sound effects but as musical instruments. Every film studio has a library of "sound effects" recorded on film. With a film phonograph it is now possible to control the amplitude and frequency of any one of these sounds and to give to it rhythms within or beyond the reach of the imagination. Given four film phonographs, we can compose and perform a quartet for explosive motor, wind, heartbeat, and landslide.

Power and profit structures're out of cahoots with current technology. Aware of new inventions, corporations put them aside, waiting for competitive reasons until they're obliged to use new gimmicks.

I needed another basis for musical structure. This I found in sound's duration parameter, sound's only parameter which is present even when no sound is intended.
