Arnold Schoenberg or Schönberg (13 September 1874 – 13 July 1951) was an Austrian composer and painter. He was associated with the expressionist movement in German poetry and art, and leader of the Second Viennese School. With the rise of the Nazi Party, by 1938 Schoenberg's works were labelled as degenerate music because he was Jewish. He moved to the United States in 1934. More: en.wikipedia.org.
