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.
