Step-by-step explanation:
Jackson Pollock created his paintings, such as 'Rhythm (Number 30)', by using a technique called drip painting. He laid his canvas on the floor and dropped, dripped, or dribbled paint onto it. Sometimes, he even threw paint directly from the can or punched holes in paint cans to let the paint run out. The resulting paintings had loose and improvisational compositions, with lines formed by the motion of the paint. Pollock's goal was to capture the loose and syncopated rhythms of jazz music, which he was a fan of.
