Aesthetic preferences for combinations of color and music

135 university undergraduates heard 12 preludes from J. S. Bach's Well-tempered Clavier (Vol. 1) while viewing alternating red, yellow, green, and blue colored lights. Their task was to rank-order the lights according to how well they "matched" the music. Preferences for combinations of color and music differed depending on whether the music was in a major or a minor key. The present findings along with those of some earlier studies suggest that aesthetic experience may be heightened when colors are seen that match the mental images music evokes.
