PURPOSE:To freely set the frequency of plural additional sounds during play by detecting how much frequency a keyed pitch name is separated from a prescribed reference sound by a chord designation key area and generating a sound, which is separated from the played sound only by this detected frequency, as a chord. CONSTITUTION:When keying in a chord designation key area 206 is detected, the pitch name separated from the keyed playing sound only by the detected frequency, with which the keyed pitch name is separated from the reference sound, in a playing key area 207 is obtained. Play information corresponding to the keyed playing sound and the chord obtained in a chord arithmetic means 105 are generated. Thus, according to how to key in the chord designation key area 206 and the number of keying in the chord designation key area 206, it can be freely set during the play how much separated sound is added to the playing sound keyed in the playing key area 207 and how many sounds are added to the playing sound. |
