PURPOSE:To improve the accompanying sound of a bass instrument or the like without deteriorating the attenuation ratio of a singing voice by leading an output from a subtracting means to a sound quality correcting means and emphasizing a frequency component <=the means part by a sound quality correcting means. CONSTITUTION:Partial signals such as a singing signal, a bass instrument signal and a rhythm instrument signal are included in respective channels of a multichannel in common and attenuated by the subtracting means 3. The signal is relatively emphasized in a low frequency area <=the means part on the basis of the characteristics of the sound quality correcting means 7. Consequently, a singing sound is also emphasized together with the emphasis of a bass instrument sound or a rhythm instrument sound and the whole level can be increased without deteriorating the ratio of accompanying sound to a singing voice in a low frequency area, i.e. the attenuation effect of singing voice in the low frequency area. Thereby, the bass instrument sound or rhythm instrument sound can be easily audible and a singing lesson can be easily executed.
