A drum key for adjusting the bolts that secure and tune the drum heads or
skin that close one or more ends of a drum. The key is constructed in an
elongated body with one end having a socket configured for engaging onto
the head of a tightening bolt used to tighten and tune the drum head or
skin. When the body of the key is articulated arms or wings embodied
within the body of the key extend, deploy or spread to provide a leaver
arm for tightening the tuning bold on a drum. After the tightening and or
tuning operation is complete, the arms or wings are securable back within
the body of the drum key.
