Abstract expressionism
Technically Surrealism was an important predecessor for Abstract expressionism with its emphasis on spontaneous, automatic or subconscious creation. Jackson Pollock's dripping paint onto a canvas laid on the floor is a technique that has its roots in the work of André Masson. Another important early manifestation of what came to be abstract expressionism is the work of American Northwest artist Mark Tobey, especially his "white writing" canvases, which, though generally not large in scale, anticipate the "all over" look of Pollock's drip paintings.
