ABSTRACT:
Disclosed are a chord detecting/storing apparatus and an accompaniment information processing apparatus. The chord detecting/storing apparatus designates tones consisting of a chord on a keyboard, and extracts one of the designated notes. Based on the extracted note, the apparatus prepares a row of note bits excluding at least one note. Using this note bit row as an address, the apparatus searches for a chord table in advance where chord information is stored to correspond to each pattern for a row of note bits, and reads out searched chord information to detect a chord.
The accompaniment information processing apparatus detects component tones of a chord when the chord is designated from the keyboard, and generates chord information. The accompaniment information processing apparatus produces specific tone information in association with the generated chord information and correlates the specific tone information with the chord information before storing both information items.
