Abstract art is art that does not attempt to represent an accurate depiction of a visual reality but instead uses shapes, colours, forms and gestural marks to achieve its effect

Formalism is the study of art based solely on an analysis of its form – the way it is made and what it looks like

Constructivism was a particularly austere branch of abstract art founded by Vladimir Tatlin and Alexander Rodchenko in Russia around 1915

Postmodernism can be seen as a reaction against the ideas and values of modernism, as well as a description of the period that followed modernism's dominance in cultural theory and practice in the early and middle decades of the twentieth century.
