FIELD: engineering of percussion musical instruments.
SUBSTANCE: percussion musical instrument contains at least one reverberating element in form of rotation body with stepped generatrix and even-sized bases, with coaxial through hollow, thickness of peripheral portion of which, counted from greater base, decreases in radial direction, held discontinuously in points, positioned along circle within limits of lesser base. Through hollow has number of steps equal to seven, while with increase of distance in axial direction, counted from greater base, size of hollow decreases in radial direction. Steps of both generatrix lines, counted and numerated in axial direction, are selected in couples, similar to each other.
EFFECT: increased frequency of sound and decreased material consumption while providing for polyphony in octave spectrum.
