Last week in my class, a student asked me what is abstract art. He wanted me to talk about it because he had never done it. This was his first experience in an abstract painting class. He was, by profession, a microbiologist. Thinking it is such a broad subject, I told him to ask me some questions.
Then, coming home, immersed in my life of abstractions, I thought it is, basically, about composition. Within that, there is balance and tension, focus, image, ground: all the elements that, put together, make up a composition. When the composition adds up, the painting does its job, tells its story, connects with the viewer–all of that.
