ABSTRACT:
A mechanism for heating the head of a percussion drum includes a pair of membranes disposed in tight adjacency to each other and tautly held with respect to the annular drum wall and a wire loop electrically connected to an external source of electricity and being tightly sandwiched concentrically between the membranes for insuring heat dissipation radially outwardly and inwardly therefrom with a minimization of the heat being lost to ambient air before the primary purpose of thorough membrane heating has first been realized.
