ABSTRACT:
When a first bar-division determination section determines that the bass note changes in a bar or when a second bar-division determination section determines that the degree of change in the chord in the bar is large, a chord-name determination section divides the bar and detects chords. This operation allows correct chords to be detected even when the chord changes within a bar, while the bass note is maintained.
