The inversion type of chord is determined from the reference part sound, and then sounds of the chord are produced in accordance with the inversion type thus determined. The apparatus determines, as production of sounds of chords proceeds, a reference part sound of a present chord in accordance with a musical interval relationship of component sounds of the present chord to another reference part sound of a preceding chord and in accordance with a preset rule. The inversion type of the present chord is determined by the reference part sound.
