ABSTRACT:
An electronic musical instrument has a minus-one function to effect switching between full automatic performance and semi-automatic performance in which programmed musical tones are generated as automatic accompaniment except for melody and obbligato parts. A performance data memory records automatic performance data. A keyboard has a right key region allotted with the melody part and a left key region allotted with the obbligato part. A CPU controls the automatic performance according to operation of various switches including a song selecting switch, a start/stop switch and a minus-one switch for setting the minus-one mode. Under the minus-one mode of the automatic performance, instant musical tones are generated in response to the operation of the keyboard, while corresponding programmed musical tones are inhibited for the melody and obbligato parts when the key operation is detected on either of the right and left key regions.
