Arnold Schoenberg

Arnold Schoenberg or Schönberg (, ; ; 13 September 187413 July 1951) was an Austrian-American composer, music theorist, painter, teacher, and writer. Among the first modernist composers to write music of dense motivic relations saturating the musical texture, he propounded concepts like developing variation, the emancipation of the dissonance, and the "unity of musical space".

Schoenberg's early works, like ''Verklärte Nacht'' (1899), represented a Brahmsian–Wagnerian synthesis on which he built. Mentoring Anton Webern and Alban Berg, he became the central figure of the Second Viennese School. They consorted with visual artists, published in ''Der Blaue Reiter'', and wrote atonal, expressionist music, attracting fame and stirring debate. In self-portraits Schoenberg emphasized his intense gaze; in music like the String Quartet No. 2 (1907–1908), ''Erwartung'' (1909), and ''Pierrot lunaire'' (1912), he visited extremes of emotion. While working on ''Die Jakobsleiter'' (from 1914) and ''Moses und Aron'' (from 1923), Schoenberg confronted popular antisemitism by returning to Judaism and substantially developed his twelve-tone technique. He systematically interrelated all notes of the chromatic scale in his twelve-tone music, sometimes admitting tonal elements".}} and often exploiting hexachords and combinatoriality.

Schoenberg resigned from the Prussian Academy of Arts (1926–1933), emigrating as the Nazis took power; they proscribed his (and his students') music as "degenerate". He taught in the US, including at the University of California, Los Angeles (1936–1944), where facilities are named in his honor. He explored writing film music (as he had done idiosyncratically in ''Begleitungsmusik zu einer Lichtspielscene'', 1929–1930) and wrote more tonal music, completing his Chamber Symphony No. 2 in 1939. With citizenship (1941) and US entry into World War II, he satirized fascist tyrants in ''Ode to Napoleon'' (1942, after Byron), deploying Beethoven's fate motif and the . Post-war Vienna beckoned with honorary citizenship, but Schoenberg was ill as depicted in his String Trio (1946). As the world learned of the Holocaust, he memorialized its victims in ''A Survivor from Warsaw'' (1947). The Israel Conservatory and Academy of Music elected him honorary president (1951).

His innovative music was among the most influential and polemicized of the 20th century. At least three generations of composers extended its somewhat formal principles. His aesthetic and music-historical views influenced musicologists Theodor W. Adorno and Carl Dahlhaus. The Arnold Schönberg Center collects his archival legacy. Provided by Wikipedia
