Expressionism
Expressionism was a cultural movement originating in Germany at the start of the 20th century. It is exhibited in many art forms, including: painting, literature, theater, dance, film, architecture and music. Its typical trait is to present the world from a subjective perspective, violently distorting it to transmit personal moods. In general, the term refers to art that expresses intense emotion rather than physical reality.
A few of the Expressionists were: Klee, Van Gogh, Munch, Kandinsky, Chagall, deKooning and Pollock. Influenced by the Fauves, Expressionists worked with arbitrary colors as well as jarring compositions to capture vivid emotions. Kandinski believed that with simple colors and shapes, the spectator could perceive the moods and feelings of the paintings. Therefore, he make the move to abstraction. ……from Wikipedia
