Paul Hindemith was a prolific German composer, violist, violinist, teacher and conductor. In the 1920s, he became a major advocate of the Neue Sachlichkeit (new objectivity) style of music. Notable compositions include his song cycle Das Marienleben (1923), Der Schwanendreher for viola and orchestra (1935), and opera Mathis der Maler (1938). Hindemith's most popular work, both on record and in the concert hall, is likely the Symphonic Metamorphosis of Themes by Carl Maria von Weber, written in 1943.
