Symphony, Op. 21 is a symphony by Austrian composer Anton Webern, completed in 1928. The work employs twelve-tone serial techniques, concise and highly concentrated textures and transparent orchestration that exemplify Webern's mature atonal style, marking a notable example of early 20th-century serialism in his late output.
