PURPOSE:To provide an automatic accompanying device which can take a melody performance form using the whole key area even in the case an automatic accompanying performance by reproducing code sound information is performed. CONSTITUTION:A performance information generating means generates key-push information corresponding to a performance operation, and a reproducing means outputs first chord information stored in advance. Subsequently, in the case a selecting means selects first chord information, a chord detecting means outputs first chord information and key-push information, and an automatic accompanying means 9 performs automatic accompaniment based on this first chord information. In such a way, even in the case an automatic accompanying performance is performed in accordance with code sound information, a melody performance using the whole key area can be performed. |
