ABSTRACT OF THE DISCLOSURE A method of tensioning a musical drum is disclosed using a device for torquing the tension rods of the drum. The device has a housing having a central aperture and a concentric upper recess. The upper recess has a first partial annular groove and a concentric second annular groove. A shaft assembly is rotatably disposed in the central aperture and the upper recess and is adapted to receive at its lower end means for gripping a tension rod. The shaft assembly has a stop portion disposed in the first partial annular groove for positive rotation of the shaft assembly beyond a predetermined range of rotation of the housing. Biasing means disposed in the second annular groove is connected between the shaft assembly and the housing, for applying torque to a gripped tension rod upon turning the housing within said predetermined range. The drum is tensioned, and thus tuned to pitch, by torquing the drum tension rods to a predetermined torque.
