Symphony, Op. 21 was composed by Anton Webern between 1927 and 1928. It was his first twelve-tone orchestral work. The two-movement work lasts 10–20 minutes and is full of Alpine topics, abstraction, and intricate musical form, including some fixed register. The Symphony was influenced by Gustav Mahler. Alexander Smallens conducted the world premiere at New York's Town Hall on 18 December 1929.
