In an electronic musical instrument of waveshape memory type, a waveshape memory stores waveshape data which covers from start to end of a musical tone and which varies litle by little in shape, amplitude and/or cyclic period as the waveshape extends to the succeeding cycles. A start address from which the waveshape memory begins to be read is controlled by expression control such as a key touch response structure or expression pedal, so that the tone color, level and/or pitch of a produced tone is varied according to the expression control.
