Late in life, maverick composer Cage decided to stop finding ‘alternatives to harmony’. The results have been rediscovered by a new generation of musicians

In the summer of 1990 John Cage gave a lecture at the International New Music gathering in Darmstadt, Germany, and effectively admitted defeat. The then 76-year-old US composer announced that his philosophical ideas of freedom and collaboration, concepts built into his avant garde musical compositions since the 1950s, had failed to influence reality. The world had got worse, not better. It was “a life spent … beating my head against a wall”, he announced. There was, however, one consolation. “I no longer consider it necessary to find alternatives to harmony,” he said. “After all these years I am finally writing beautiful music.”

Cage was referring to his Number Pieces, around 40 late works named after the quantity of performers involved (from 1 to 101) in which individual musicians could choose when and how long to play (within designated time brackets) resulting in often quiet and meditative pieces, a marked contrast to the previous, often abrasive compositions he’d built his 40-year reputation on.
