"For the Birds" can be seen as a persiflage to John Cages' aleatoric work. Basically it is an experimental test arrangement denoted to study randomness, it's generative force and the correlation between noise and sound.
Technically the sound is generated as follows:
Two opposing hairdryers set a ball inside a glas cube in motion. Light sensors underneath the glas, influenced by the moving ball, trigger twelve chromatic tones on a circuit bended keyboard.
