The document discusses synesthesia, a neurological condition where senses are crossed and one can see sounds, taste music, or feel colors. It provides examples of the artist Wassily Kandinsky, who experienced synesthesia and whose abstract paintings were influenced by the colors and forms he associated with music. Kandinsky believed abstract art had a more direct appeal, and his paintings Composition VII and Impression II (Concert) were directly inspired by his synesthetic experiences of music.
