 One of the most literal examples of this new synthesis is "The Bavarian Don Giovanni" (1919).After returning home, Klee painted his first pure abstract, "In the Style of Kairouan" (1914), composed of colored rectangles and a few circles.The colored rectangle became his basic building block, what some scholars associate with a musical note, which Klee combined with other colored blocks to create a color harmony analogous to a musical composition.
