Variations V (1965, 7.5MB, 2:22 min)

‘John Cage made ‘Variations V’ in 1965 for the Merce Cunningham Dance Company.
He and David Tudor settled on two systems for the sound to be affected by movement:
directional photocells aimed at the stage lights, so that the dancers triggered sounds as
they cut the light beams with their movements, and a series of antennae.
When a dancer came within four feet of an antenna a sound would result.
Cage, Tudor, and Gordon Mumma operate equipment to modify and determine
the final sounds.’ – from mediaartnet.
