Action painting partially coincident with Tachisme
Action painting, sometimes called "gestural abstraction", is a style of painting in which paint is spontaneously dribbled, splashed or smeared onto the canvas, rather than being carefully applied. The resulting work often emphasizes the physical act of painting itself as an essential aspect of the finished work or concern of its artist.Background
The style was widespread from the 1940s until the early 1960s, and is closely associated with abstract expressionism (some critics have used the terms "action painting" and "abstract expressionism" interchangeably). A comparison is often drawn between the American action painting and the French tachisme. The New York School of American Abstract Expressionism (1940s-50s) is also seen as closely linked to the movement.The term was coined by the American critic Harold Rosenberg in 1952, in his essay "The American Action Painters",  
and signaled a major shift in the aesthetic perspective of New York School painters and critics. According to Rosenberg the canvas was "an arena in which to act".  The actions and means for creating the painting were seen, in action painting, of a higher importance than the end result. While Rosenberg created the term "action painting" in 1952, he began creating his action theory in the 1930s as a critic. While abstract expressionists such as Jackson Pollock, Franz Kline and Willem de Kooning had long been outspoken in their view of a painting as an arena within which to come to terms with the act of creation, earlier critics sympathetic to their cause, like Clement Greenberg, focused on their works' "objectness." Clement Greenberg was also an influential critic in action painting, intrigued by the creative struggle, which he claimed was evidenced by the surface of the painting.  To Greenberg, it was the physicality of the paintings' clotted and oil-caked surfaces that was the key to understanding them. "Some of the labels that became attached to Abstract Expressionism, like "informel" and "Action Painting," definitely implied this; one was given to understand that what was involved was an utterly new kind of art that was no longer art in any accepted sense. This was, of course, absurd." – Clement Greenberg, "Post Painterly Abstraction".
Rosenberg's critique shifted the emphasis from the object to the struggle itself, with the finished painting being only the physical manifestation, a kind of residue, of the actual work of art, which was in the act or process of the painting's creation. The newer research tends to put the exile-surrealist Wolfgang Paalen in the position of the artist and theoretician who used the term "action" at first in this sense and fostered the theory of the subjective struggle with it. In his theory of the viewer-dependent possibility space, in which the artist "acts" like in an ecstatic ritual, Paalen considers ideas of quantum mechanics, as well as idiosyncratic interpretations of the totemic vision and the spatial structure of native-Indian painting from British Columbia. His long essay Totem Art (1943) had considerable influence on such artists as Martha Graham, Barnett Newman, Isamu Noguchi, Jackson Pollock and Mark Rothko; Paalen describes a highly artistic vision of totemic art as part of a ritual "action" with psychic links to genetic memory and matrilinear ancestor-worship.Over the next two decades, Rosenberg's redefinition of art as an act rather than an object, as a process rather than a product, was influential, and laid the foundation for a number of major art movements, from Happenings and Fluxus to Conceptual, Performance art, Installation art and Earth Art.
