A phrase tonality analyzer determines a key of each phrase to provide a correct succession of keys of the melody. With this arrangement, the music apparatus can detect, from the melody, a modulation (change of key). A chord progression database is searched to assign an appropriate chord pattern to each phrase. Thus, the melody is harmonized with a natural and real chord progression. A style analyzer tests a melody phrase for a preselected music style and labels it with style-matched if it meets the preselected music style. A chord pattern characteristic of the preselected music style is selected from a chord progression database of the same music style to harmonize the style-matched phrase. Thus, the melody agrees with the harmonizing chord progression in terms of music style.Field of SearchElectrical musical tone generationData storage Digital memory circuit (e.g., RAM, ROM, etc.) Sampling (e.g., with A/D conversion) Waveform memory Note sequence Accompaniment Rhythm Chords Accompaniment Rhythm Tempo control Chords Arpeggio Note sequence Accompaniment (e.g., chords, etc.) Rhythm Tempo control | |
