Autumn Rhythm (Number 30)

Step into the world of Jackson Pollock, and you'll find no brushes touching canvas in the usual way. For this massive work, painted in 1950, the artist laid his canvas flat on the floor and moved around all four sides of it, dripping and flinging house paint with sticks and hardened brushes. The result is a tangle of black, white, and brown lines that seem to dance across the surface. Pollock called this approach "action painting," and it became the signature of a movement known as Abstract Expressionism, which put American art on the map after World War II.

Despite its name, you won't find any falling leaves or autumn trees here. The title came after the painting was finished, suggested by the warm earthy colors and the feeling of energy and movement, like nature in motion. Pollock was careful to point out that his work wasn't random. He knew exactly what he was doing, controlling the flow of paint with the rhythm of his whole body. Some people see chaos when they look at this piece, while others see a kind of music made visible. Either way, it invites you to stop searching for a picture and simply feel the motion instead.
