SECTIONALIZED MUSICAL DRUMS ABSTRACT OF THE DISCLOSURE The complete drum comprises two, axially-separable, generally cy- lindrical sections, which are open, inwardly, toward each other, each of these two sections having but one playing head, so that the two heads are disposed respectively at the outer ends of the cylindrical assembly. When the open ends of these two basic sections are axially spaced-apart to pro- vide an annular gap between them, the space within said sections communicates with the ambient air, through said gap, substantially uniformly around the periphery of the drum. This construction, with gap, is intended to provide any desired increase in volume, and a great variety of tonal modifications. Appropriate mechanism are provided for adjustably varying the size of the gap, or for closing it altogether; whereby the volume, pitch, dynamics, and tonal characteristics of the drum may be varied. This may be done by using adjust- able holding means, and/or by using perforate or imperforate cylindrical fil- ler pieces.
