摘要： A percussion instrument mount includes a base that supports a percussion instrument in a playing position. The percussion instrument mount also includes a swing arm that is coupled to the percussion instrument, and is also coupled to the base via a joint such that the swing arm rotates about the joint from an equilibrium position in response to a playing impact on the percussion instrument. The percussion instrument mount still further includes a playing impact energy absorber that provides a restoring force to the swing arm so as to return the swing arm to the equilibrium position.
