Abstract: A heel-operated device of a foot pedal-actuated instrument of a drum set enables a user to play two instruments of the drum set using the same foot to actuate separate foot pedals. One foot pedal controls the play of one instrument and another foot pedal controls the play of the second instrument of the drum set. At least one of the two instruments is a drum, and the other may be cymbals or bell or another drum. The heel-operated device includes a heel-actuated member, a rod hinged at one end of the heel-actuated member and pivotally coupled to one foot pedal for depression thereof by pressure of the heel of a foot of the user on the heel-actuated member to play the first instrument while allowing the tip of the same foot of the user freedom to operate the other foot pedal for actuating the second instrument. The base member is hinged to an end of the heel-actuated member opposite the end thereof at which the rod is hinged, to provide stability of the heel-operated device during play of the drum set.
