ABSTRACT:
A sealing pad assembly for closure of a wind instrument's tone hole and device for containing and securing the pad assembly. The pad's felt backing provides a soft support over the sealing surface of the tone hole to minimize noise but has a firm outer and central regions to minimize deformation of the pad surface and damage from abrasive contacts and to optimize the instrument's tone. The pad cup and retainer are designed to allow the retainer to pivot when the pad is leveled. As a result, stress is relieved which could otherwise damage the pad's surface or cause the pad nut to break away from the pad cup.
