A drum stick accessory includes a pair of support members defining a parting plane and an elongate channel defined by elongated substantially parallel recesses on opposing sides of the parting plain. Closed resilient loops draw the support members together to minimize the channel cross-sectional dimensions. Restoring forces in the loops tend to revert the support members to the contracted condition. Insertion of a drum stick into the elongate channel separates the members and moves them from the contracted condition to an expanded condition against the action of the loops and the accessory can be reliably frictionally retained on the shaft of the drum stick due to restoring forces urging the support members against the drumstick. Hitting the drum stick as a percussion instrument provides additional sounds produced, for example, by steel shot within compartments formed in the supporting members or jingles attached thereto.
