WHAT MAKES AN ARTWORK ABSTRACT?
"Of all the arts, abstract painting is the most difficult. It demands that you know how to draw well, that you have a heightened sensitivity for composition and for colors, and that you be a true poet. This last is essential."
Abstract art does not depict a person, place, or thing of the world. Composition, color, shapes, brushstrokes, size, scale and simply the steps to create comprises Abstract painting. Works that don't have a "thing" allow for the viewer to engage with the work in a powerful way -- usually form and color become the "object" of the piece.
