ABSTRACT:
A multi-annular musical drum instrument formed from a plurality of axially aligned permanently connected rings. Each ring formed of a multi-annular ring of laminated plywood, a solid wood or other desireable material. Each ring is non-jointed and undivided in the circumferential direction so as to be formed of a single piece rather than a composite of sections so as to provide uniform vibratory characteristics. One or more of the rings functons as a sounding ring having a greater outer radius than the other shell rings. Such sounding rings receive a connection to a respective drum head. Two rings form outer rings of the cylindrical shell contacting the respective drum heads. Either or both of the two may be rounded to decrease the overtones of the drum head, pointed to increase the overtones of the drum head, or flat so as not to alter the overtones of the drum head. The simplified construction provides a drum having a natural sound without rattling noises or a tin sound elsewhere caused by moving parts and extraneous brackets.
