Bohuslav Jan Martinů (Czech: (About this soundlisten); December 8, 1890 – August 28, 1959) was a Czech composer of modern classical music. Martinů wrote 6 symphonies, 15 operas, 14 ballet scores and a large body of orchestral, chamber, vocal and instrumental works. He became a violinist in the Czech Philharmonic Orchestra, and briefly studied under Czech composer and violinist Josef Suk. After leaving Czechoslovakia in 1923 for Paris, Martinů deliberately withdrew from the Romantic style in which he had been trained. In the 1930s he experimented with expressionism and constructivism, and became an admirer of current European technical developments, exemplified by his orchestral works Half-time and La Bagarre. He also adopted jazz idioms, for instance in his Kitchen Revue (Kuchyňská revue).
