Wassily Kandinsky was a synesthete for whom sight and sound were intrinsically linked—he could hear color and see sound. His appreciation of music and his painted interpretations thereof played out in his pioneering Abstract art. His best-known painting, Squares with Concentric Rings, is a color study in which he experimented with various color combinations and explored how color and form interact to evoke an emotional response. Such exercises informed Kandinsky’s work as a progressive educator (the art school he helped found in 1902 was among the first to admit women) and shaped his philosophy as an art theorist.
