Abstract
A percussion instrument and a tension applying method are provided. A frame member where an outer edge of a membrane member is connected is arranged at the other side in the axial direction of a frame, and the frame member is tightened radially inward by a tension ring. The frame member has a predetermined elasticity, and a diameter of the frame member is reduced by a tightening force of the tension ring; thus, the tension may be applied to the membrane member by reducing the diameter of the frame member. That is, an edge portion of the membrane member may be uniformly pressed radially inward over the entire circumference by reducing the diameter of the frame member, and thus the tension may be uniformly applied to the entire membrane member.
