Chord-Based Musical Composition and Incorporating it into Auto-Accompaniment Instrument

This paper presents the easy way to compose musical composition for non-musicians. Firstly, we developed a chord-based music composition program, and then incorporated it into the auto-accompaniment program. Namely, the only way we have to do is to select a chord and put it to special program which called "the chord-based music composition program" and then the composition program creates the rest of the chords automatically. Consequently, non-musicians overwrite their own melodies in accordance with created chords. Finally, they can perform their own music with the sound of master-keyboard and other sound sources by using the auto-accompaniment program.
