ABSTRACT:
In an automatic accompaniment-playing apparatus, when an accompaniment pattern corresponding to a detected chord is not stored as information in a memory, an accompaniment pattern as information read from the memory in accordance with the priority level is changed so as to be suited to the detected chord. In a chord detecting apparatus, inversion modes are obtained based on an information-on-depressed-key so as to determine chords relative to the inversion modes obtained in this way. Then, the chords determined in this way are weighted, and a chord weighted at the maximum level out of the chords thus weighted is determined as one based on the above information-on-depressed-key.
