Abstract: A method for teaching musical theory wherein each note of the chromatic scale is associated with one of three markings, preferably incorporating three distinct colors, making a repeating pattern up and down the musical scale. The preferred colors are silver, black, and gold. Some instruments are adapted to use with the system by marking playing positions on the instrument, such as keys or fingering positions, according to the marking system. Sheet music may also be adapted to embodiments of the method by indicating notes in the color associated with that note. Note recognition and musical theory, including chord structures, are taught using patterns of colors corresponding to different notes, chords, musical keys, etc.

Abstract: First, it is central to point out that the rules of traditional Music Theory from Pythagoras' monochord to theories of harmony from Ricardo Goldman, Walter Piston, and Arnold Schoenberg have been researched and applied to the development of the Cubichord System™, and that Cubichord believes this System does not in any way contradict nor superseede those explanations of Music Theory and Harmony.30 30 Australian Michael Furstner at jazclass, on the internet, introduced me to Music in 2000. Furthermore, the principles of mathematics and logic specifically apply, especially the basic axiom that if A=B, and B=C, then A=C. That is, if an event or chord is presented in one color it logically applies for another and works the same, using the traditional major chord tones. This is true because of the perfect symmetry of the Cubichord™ system, and has thus far proved true and correct for any chord or interval applied within the system or as commonly used in music.
