Arnold Schoenberg

Arnold Schoenberg or Schönberg (13 September 1874 – 13 July 1951) was an Austrian and American modernist composer, music theorist, teacher. He was associated with developing variation, the emancipation of the dissonance, and twelve-tone composition. He taught composition in Vienna and at the Prussian Academy of Arts (1925–1933), resigning in anticipation of Nazi Germany's civil–service restrictions. He defiantly reaffirmed his Judaism before immigrating to the United States, where he taught at the University of California, Los Angeles (1936–1944).
