Wikipedia Overview

Paul Hindemith was a German and American composer, music theorist, teacher, violist, and conductor. He founded the Amar Quartet in 1921, touring extensively in Europe. As a composer, he became a major advocate of the Neue Sachlichkeit style of music in the 1920s, with compositions such as Kammermusik, including works with viola and viola d'amore as solo instruments in a neo-Bachian spirit. His other notable compositions include the song cycle Das Marienleben (1923), the oratorio Das Unaufhörliche (1931), Der Schwanendreher for viola and orchestra (1935), the opera Mathis der Maler (1938), and the symphony Mathis der Maler (1934), the Symphonic Metamorphosis of Themes by Carl Maria von Weber (1943), and the oratorio When Lilacs Last in the Dooryard Bloom'd (1946), a requiem based on Walt Whitman's poem. Hindemith and his wife emigrated to Switzerland and the United States ahead of World War II, after worsening difficulties with the Nazi German regime. In his later years, he conducted and recorded much of his own music.
