Arnold Schoenberg 13 September 1874 – 13 July 1951

Schoenberg was an Austrian and later American composer, associated with the expressionist movement in German poetry and art, and leader of the Second Viennese School. 

Schoenberg's approach, both in terms of harmony and development, is among the major landmarks of 20th century musical thought; at least three generations of composers in the European and American traditions have consciously extended his thinking or, in some cases, passionately reacted against it. During the rise of the Nazi Party in Austria, his music was labeled, alongside jazz, as degenerate art.

Five Orchestral Pieces by Arnold Schoenberg is a set of atonal pieces for the full orchestra. They all last between one and five minutes and are not connected to each other by the use of any thematic ideas. Peripetie is in the style of expressionism.
