Variations VII is a piece of contemporary music written by John Cage. It was first performed in 1966 as part of the 9 evenings concert series in New York. It is largely stochastic with an indeterminate length and use of unrecorded technological produced or electrically amplified sound. In the words of Cage the sounds had to be in the air at the moment of performance. Photocells were used to turn on and off the sound sources.
