Pascal Dusapin (29th May, 1955) is a French composer born in Nancy. He studied fine art, science and aesthetics at the Sorbonne in Paris. One of France's best-known living composers, his works have been performed worldwide. At the suggestion of Franco Donatoni he attended the seminars of Iannis Xenakis from 1974 until 1978. Both composers had a deep influence on his early works but he soon developed his own style based on the use microtonality and the superposition of several atonal lines, creating a kind of "atonal heterophony".
