Expressionism is the tendency of an artist to distort reality for an emotional effect; it is a subjective art form. Expressionism is exhibited in many art forms, including painting, literature, theatre, film, architecture and music. The term often implies emotional angst. In a general sense, painters such as Matthias Grünewald and El Greco can be called expressionist, though in practice, the term is applied mainly to 20th century works.
Although it is used as term of reference, there has never been a distinct movement that called itself "expressionism", apart from the use of the term by Herwald Walden in his polemic magazine Der Sturm in 1912. The term is usually linked to paintings and graphic work in Germany at the turn of the century which challenged the academic traditions, particularly through the Die Brücke and Der Blaue Reiter groups.
The term was coined by Czech art historian Antonín Matějček in 1910 as the opposite of impressionism: "An Expressionist wishes, above all, to express himself….[An Expressionist rejects] immediate perception and builds on more complex psychic structures….Impressions and mental images that pass through mental peoples soul as through a filter which rids them of all substantial accretions to produce their clear essence […and] are assimilated and condense into more general forms, into types, which he transcribes through simple short-hand formulae and symbols." (Gordon, 1987)
