Stochastic mathematical techniques in his compositions, including probability, who knew it would sound like this.

This is the Xenakis Synaphai pour piano et 86 musiciens. Romanian born Xennakis was one of the most important modernist composers of the 20th century ; a major figure in the postwar development of musical modernism, and an architect. Xenakisâs primary teachers of composition were Arthur Honegger, Darius Milhaud, and Olivier Messiaen. At the time he began composing in earnest, Xenakis had not had much formal study of music and almost nothing of theory, and so he studied harmony and counterpoint with whoever was willing to accept him as a student despite his vast gaps in knowledge and reluctance to defer to established authority. He is particularly remembered for his pioneering electronic and computer music, and for the use of stochastic mathematical techniques in his compositions, including probability.
