The striking member for use with a percussion instrument is a vibration-inducing and flexing variation of a conventional unitary or one-piece drum stick, drum mallet or the like. The striking member includes a stick having opposed first and second ends, and a hollow shell having an opening formed through a lower end thereof. The first end of the stick is adapted for grasping by the user, and the second end is inserted through the opening, into an open interior region of the hollow shell. The hollow shell is secured to the stick, and flexes when striking a surface, such as a drum, for example. An elastic material may further be received within the hollow shell, and may at least partially fill the open interior region thereof in order to provide further elastic properties for the head of the striking member.
