A method and apparatus for composing and performing music on an electronic instrument in which individual chord progression chords can be triggered in real-time, while simultaneously making the individual notes of the chord, and/or possible scale and non-scale notes to play along with the chord, available in separate fixed-locations on the instrument. The method of composition involves the designation of a chord progression section on the instrument, then assigning chords to this chord progression section according to particular song keys and scales. Further, as each chord is played in the chord progression section, the individual notes of the currently triggered chords are simultaneously made available for playing in a separate fixed location on the instrument. Fundamental and alternate (fifth) notes of each chord may be made available in separate fixed locations for composing purposes. Possible scale and non-scale notes, to play along with the currently triggered chord, can also be simultaneously made available for playing in fixed locations on the instrument. Finally, a method of storing all composition data in memory, in which all of this sequenced data can later be retrieved and performed by the user from a fixed location on the instrument, and on a reduced number of keys.
