ABSTRACT:
In the construction of a damper assembly of pianos, the conventionally used long-sized damper wire is replaced by a pair of separate short-sized lever components operationally related to each other via an additional intermediate damper lever for stabilized action of the assembly even without provision of the conventionally used guide rail. A shorter length damper wire joins the upper lever component to the damper head.
