To provide a drum performance form improvement support system which enables a player to practice the stick control giving priority to extensor muscles even with sticks which the user ordinarily uses to play a drum, and is capable of correcting movement of his or her wrists to that giving priority to extensor muscles.

The drum performance form improvement support system includes: an electronic drum pad which outputs a beat applied to a drumhead by a drum player, as a detection signal on the basis of beat timing; delay adding means which adds a delay time equal to or shorter than an auditory discrimination threshold of the drum player, to the detection signal to output a resultant signal as a delay signal; and an electronic sound source which outputs an electronic beat sound to the drum player on the basis of the delay signal.
