Abstract: Disclosed is a system for colorizing music for converting black and white musical scores into colorized musical scores through the use of a method that can be implemented by a computer wherein each whole tone and half tone is assigned a unique color and pattern, respectively, using a septuary system of colors. The unique colors and patterns are applied to piano keyboards, keyboard guides and to other musical instruments. Colorized musical scores in standard format or, alternatively, in a linear format on one or more computer screens or special display devices are displayed for viewing by the musician. The musical instruments are colored according to the musical score notes to facilitate playing of music.
