Abstract
A musical performance apparatus is provided with a tone generation circuit 15 and a sound system 16 for emitting musical tones of musical instruments and control tones corresponding to musical score data SD which controls a musical score display apparatus 20. The tone generation circuit 15 has a tone volume adjustment circuit 15a3 which changes tone volume of only the musical tones in accordance with player's instruction and maintains tone volume of the control tones at a certain tone volume. The tone generation circuit 15 also has a pan adjustment circuit 15a4 which localizes the control tones so that the control tones will be emitted only from a certain speaker. Furthermore, the musical performance apparatus is designed such that the control tones are formed only of frequency components included in a certain high frequency band. Furthermore, the tone volume of frequency components which are included in frequency components representative of the musical tones and are further included in the certain high frequency band is controlled to be lower than the tone volume of the control tones.
