Abstract
Abstract The invention concerns enhancement of the utility of drum beating apparatus, and more particularly concerns provision for adjustability and stability of drum single and dual beaters, drives therefor, and supports for the drives. Selective positioning and usage of single or dual drum beaters are provided, in modes accommodating adjustable positions of left and right foot bases associated with the drummer's feet.
