Color Field and Geometric Abstracts
Abstract painting offers the artist an opportunity to work directly and solely with the primary elements of painting: a surface, a medium, and a method of applying the medium to the surface.
Color, texture, and shape together form the eventual composition and therefore become the primary focus of the painter resulting in a particular aesthetic experience of the work for the viewer.
This aesthetic experience can be compared to experiencing a musical composition; how the notes are arranged and played creates the experience of listening to a musical composition. So too in an abstract painting (or any painting actually) how the elements of shape, color and texture interact create a visual experience. Just as no words are needed to enjoy a musical composition, so too no imagery is needed to enjoy the experience of an abstract composition.
