Expressionism

Expressionism as a musical genre is difficult to exactly define. It is, however, considered one of the most important movements of 20th Century music. The three central figures of musical expressionism are Arnold Schoenberg and his pupils, Anton Webern and Alban Berg, the so-called Second Viennese School. 

Expressionism was a modernist movement, initially in poetry and painting, originating in Germany at the beginning of the 20th century. Its typical trait is to present the world solely from a subjective perspective, distorting it radically for emotional effect in order to evoke moods or ideas. Expressionist artists sought to express meaning or emotional experience rather than physical reality.

Expressionism was developed as an avant-garde style before the First World War. It remained popular during the Weimar Republic, particularly in Berlin. The style extended to a wide range of the arts, including painting, literature, theatre, dance, film, architecture and music.

The term is sometimes suggestive of angst. In a general sense, painters such as Matthias Grünewald and El Greco are sometimes termed expressionist, though in practice the term is applied mainly to 20th-century works. The Expressionist emphasis on individual perspective has been characterized as a reaction to positivism and other artistic styles such as Naturalism and Impressionism.
