A theory of music visualization proposed by Nancy Herman postulates an association between colors and pitches of musical scales. A color raster graphics display is used to generate images of notes, chords, and chord progressions based on this theory. Temporal adjacency of notes or chords is mapped to spatial adjacency of colors, usually in a concentric pattern of squares or circles. By varying certain image parameters, different “brush stroke” effects may be obtained. Illustrations of several computer generated “musical paintings” are included, along with some original paintings for comparison.
