Abstract: A pillow muffle is a permanent and integral part of a bass drum and includes a handle provided exteriorly of the bass drum which may be easily activated by the drummer to move the pillow muffle which is disposed interiorly of the bass drum into and out of engagement with one of the drum heads to achieve desired muffling or non-muffling effects.

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.
