Swiss-German artist Paul Klee produced a large body of unconventional artwork during his lifetime. His pieces exhibited a style fusing Cubism, Surrealism, and Expressionism, which made his art difficult to classify. He mixed medias, combining oils, watercolor, inks, pastels, and more. He initially had no color sense but learned to master tonality and color theory, which he deeply explored and eventually wrote about. Klee was born into a musical family, thus learned to play the violin at a young age. He was very good, but he decided he was more interested in the visual arts, much to his parents’ dismay. He received a fine arts degree in Munich and proceeded to make art while teaching in Germany. Later in his life, Nazis deemed his art indecent, so he fled his home and found refuge in Switzerland.
