A lot of people compare paintings to music. I agree. Paintings and music come from the same creative impulse within us. To me, abstract art is like instrumental music. It conveys feelings… emotions without spelling out the whole story for you. Representational paintings (of landscapes, people, objects from the physical world) are more like songs with lyrics.
The natural world is full of abstract images. In fact, everything in the world was an abstract form until we attached labels to it. Not only the way the reflection of the sky is distorted by the moving surface of water. Not only the concentric lines in an agate, or the shifting shapes of clouds. But a flower… Those brushes of color are like little pieces of abstract art.
