Abstract

An electronic musical instrument according to the present invention is applicable to musical instruments such as electronic wind instruments, electronic rubbed string instruments and electronic stringed instruments. Parameters of a musical tone to be generated are individually and independently altered and controlled in accordance with control data corresponding to a variation tendency of performance-input data which is detected by a performance input detection section and alters with time. And in accordance with a variation tendency per a predetermined period of time of breath operation intensity and/or lip operation intensity, parameters of the musical tone having a designated pitch are individually and independently altered and controlled.
