Starts his study on a Leonard Bernstein scholarship at the Berkshire Music Center in Tanglewood, Massachusetts, USA. He performs one of his compositons at a concert in August. His tutor is the composer Yannis Xenakis.
"Yannis's classes were unorthodox. He would put up theorems up on the board; they were the theoretical bais of the Fourier series, the Osternberg principle of probability. Probability theory was the basis on which he wrote his music. His classes were on extrapolating the probability of a B flat happening in the next three or four bars. This is stochastic music, his term for an alternative school of composition through serialism, which justifies its existence by its use of Heisenberg's uncertainty principle."
