Mixing it Up
Mozart’s musical dice game is one example of how musicians and other artists have incorporated aleatoric elements into their work. Jazz improvisation means every performance is different. Cage left space for the environment to make its own music, but Xenakis took a mathematician’s understanding of randomness and created avant-garde compositions that use the orchestra in new ways. Generative techniques use random numbers to provide new music and other kinds of art on demand. Blocked creativity can be freed by deliberate injections of spontaneity.
