Arnold Schoenberg or Schönberg was an Austrian-born composer, music theorist, teacher, writer, and painter. He is widely considered one of the most important and influential composers of the 20th century. 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, Schoenberg's works were labeled degenerate music, because they were modernist and atonal. He emigrated to the United States in 1933, becoming an American citizen in 1941.
Schoenberg's approach, bοth in terms of harmony and development, has been one of the most influential of 20th-century musical thought. Many European and American composers from at least three generations have consciously extended his thinking, whereas others have passionately reacted against it.
Schoenberg was known early in his career for simultaneously extending the traditionally opposed German Romantic styles of Brahms and Wagner. Later, his name would come to personify innovations in atonality that would become the most polemical feature of 20th-century art music. In the 1920s, Schoenberg developed the twelve-tone technique, an influential compositional method of manipulating an ordered series of all twelve notes in the chromatic scale. He also coined the term developing variation and was the first modern composer to embrace ways of developing motifs without resorting to the dominance of a centralized melodic idea.
Schoenberg was also an influential teacher of composition; his students included Alban Berg, Anton Webern, Hanns Eisler, Egon Wellesz, Nikos Skalkottas, Stefania Turkewich, and later John Cage, Lou Harrison, Earl Kim, Robert Gerhard, Leon Kirchner, Dika Newlin, and other prominent musicians. Many of Schoenberg's practices, including the formalization of compositional method and his habit of openly inviting audiences to think analytically, are echoed in avant-garde musical thought throughout the 20th century. His often polemical views of music history and aesthetics were crucial to many significant 20th-century musicologists and critics, including Theodor W. Adorno, Charles Rosen, and Carl Dahlhaus, as well as the pianists Artur Schnabel, Rudolf Serkin, Eduard Steuermann, and Glenn Gould.
Schoenberg's archival legacy is collected at the Arnold Schönberg Center in Vienna. Wikipedia

Context: I see the work as a whole first. Then I compose the details. In working out, I always lose something. This cannot be avoided. There is always some loss when we materialize. But there is compensating gain in vitality.
