Abstract: A method for obtaining a chord progression based upon a diatonic major key may include the steps of casting a dodecahedron to determine the diatonic major key, casting a octahedron to determine a chord based upon the diatonic major key and casting a cube to determine a playing strategy for the chord.

Abstract: A method for generating a chord progression within a mode of a diatonic major key may include the steps of casting a first cube to define a chord matrix from a plurality of chord matrices based upon a diatonic major key, casting a second cube to select the mode of the diatonic major key from the chord matrix, casting the second cube to determine a chord progression and playing an instrument based upon the mode of the diatonic major key and the chord progression.

Abstract: A music composition method and apparatus is provided and consists of a plurality of small playing cubes each having a color-coded musical chord with a number to indicate the position of the chord within the matching color-coded musical key of a separate, larger cube indicated on each side thereof. A color-coded device is provided to guide the placement of playing cubes into sequences of chord progressions thereon after the playing cubes are cast upon a flat surface. A player can form multiple chord progressions from the chords on the top sides of the cast playing cubes and play the cast sequence of chords on their instrument thereby learning the relationship between the chords belonging to a musical key.
