Olivier Messiaen

Olivier Eugène Prosper Charles Messiaen (December 10, 1908 – April 27, 1992) was a French composer, organist, and ornithologist. His many distinguished pupils included Iannis Xenakis, George Benjamin, Alexander Goehr, Pierre Boulez, Karlheinz Stockhausen, Myung-whun Chung and Yvonne Loriod. His music is rhythmically complex; harmonically and melodically he employs a system he called modes of limited transposition.
