Abstraction; a withdrawal or generalisation away from concrete reality.
Abstract Art, is non-representational, non-figurative, or non-objective art that doesn't pursue accurate depiction of a visual reality, but explores formal relationships of shape, line, color, and movement.
The move towards pure visual abstraction was pioneered by avant-garde artists and designers in the early 20th century, and particularly in the inter-war years.
'Art which does not imitate or directly represent external reality: some writers restrict the term to non-figurative art, while others use it of art which is not representational though ultimately derived from reality. Various alternatives have been suggested (non-representational art, non objective art, concrete art) but none has been generally accepted. 'Abstract' is frequently used as a relative term, paintings being more or less abstract in treatment. The original source of an abstract painting, e.g. a landscape or still-life, may be visible or decipherable: most Cubist painting is of this sort. Simplified or geometric shapes which have no direct reference to external reality may be used exclusively, as in Mondrian's art. In a 3rd type of abstraction brush-strokes, the colour and textures of the material used suggest the development of the painting, as in Pollock's work.The idea that forms and colour in themselves can move the spectator underlies all Abstract art. Much 20th-century painting and sculpture has attempted to have, like music, no representational purpose.'
