Abstract

Abstract A removable tonal pitch indicator for a kettledrum having a foot lever-actuated adjustably tensioned drumhead or tympanum. The indicator provides a visual indication of the tonal pitch of the tympanum and includes a reciprocally movable marker which is moved upwardly or away from the tympanist to indicate a higher pitch and downwardly or toward the tympanist to indicate a lower tonal pitch of the tympanum. The desired direction of movement of the marker is attained by enclosing a relatively stiff cable in a sheath. The cable is attached to the marker and is anchored below the lever device while the sheath cooperates between the indicator housing and the lever device. Sufficient curvature is provided in the sheath/cable combination so that the movement of the lever device changes the curvature of the sheath/cable combination thereby forcing the cable to move the marker in a direction counter to the movement of the lever device. The indicator apparatus includes a plurality of adjustable pointers on either side of the marker path to permit coordination between a desired tonal pitch and the position of the marker.
