Abstract
A percussion instrument and its method of construction. The percussion instrument has an annular body with an open top and an open bottom. The annular body has multiple sections that include a first section and an opposite second section. The first and second sections join together at bending regions that are located at opposite sides of the annular body. A striking membrane is stretched taut over the open top of the annular body. An adjustment mechanism is provided that is used to selectively bend the annular body within the bending regions. Depending upon what direction the annular body is bent, the tautness of the striking membrane is either increased or decreased. This selectively alters the tone of the sound produced by the drum.
