Abstract: The connector hardware portion of each percussive musical instrument or accessory comprises strong, practical, rugged, and economical connector parts, one of which is a clamp adapted to grip solidly onto a tube at any desired rotated and axial position, and the other (second) of which is connected to a percussive instrument or accessory portion and is adapted to lock onto the clamp in a way that prevents both rotational and axial shifting relative thereto. The locking is effected in a readily removable manner, as by means including a set screw, and the relationship is such that there can be only one position of the other (second) part relative to the clamp after locking has occurred. Therefore, once the clamp is initially set at a desired rotated and axial position, there is an automatic rotational and axial "indexing" which permits any number of separations and re-connections of the two parts (and of the percussive instrument or accessory) without permitting the locked positions to change.

Abstract: A snare drum is formed of a batter head assembly and a snare head assembly fixedly held in mutually spaced apart relation by a number of support rods. A cylindrical tone ring is seated upon the snare head assembly and extends toward but short of the batter head assembly to provide a resonating chamber for the snare head.
