Tōru Takemitsu was a Japanese composer and writer on aesthetics and music theory. Though largely self-taught, Takemitsu is recognised for his skill in the subtle manipulation of instrumental and orchestral timbre, drawing from a wide range of influences, including jazz, popular music, avant-garde procedures and traditional Japanese music, in a harmonic idiom largely derived from the music of Claude Debussy and Olivier Messiaen. In 1958, the international attention he drew with his Requiem for strings (1957) resulted in several commissions from across the world, and settled his reputation as the leading Japanese composer of the 20th century. He was the recipient of numerous awards, commissions and honours; he composed over one hundred film scores and about one hundred and thirty concert works[5] for ensembles of various sizes and combinations. He also found time to write a detective novel, and appeared frequently on Japanese television as a celebrity chef. In the foreword to a selection of Takemitsu's writings in English, conductor Seiji Ozawa commented: "I am very proud of my friend Tōru Takemitsu. He is the first Japanese composer to write for a world audience and achieve international recognition."
