An adapter for the finger appendage of a brass instrument has an adapter body. An outboard side and an inboard side of the adapter body are spaced apart along a width. The adapter includes a fitting portion defining the outboard side of the adapter body and a spacer portion defining the inboard side of the adapter body. The fitting portion defines a mounting opening configured to receive the first portion of the adapter body to mount the adapter body on the finger appendage such that the spacer portion is received in the finger gap and the inboard side of the adapter body opposes the second portion of the finger appendage to define a reduced gap having a width that is less than the width of the finger gap.

A one-piece valve cluster for brass instruments that facilitates ease-of-maintenance and ease-of-repair includes an upper housing, a lower housing, a plurality of first bisected-casings, a plurality of second bisected-casings, a plurality of first bisected-ports, and plurality of second bisected-ports. The plurality of first bisected-casings and the plurality of first bisected-ports are fashioned into a first-milling face of the upper housing. Similarly, the plurality of second bisected-casings and the plurality of second bisected-ports are fashioned into a second-milling face of the lower housing. The upper housing is mounted to the lower housing to create a single piece valve cluster that can easily installed on the instrument. More specifically, the first-milling face is positioned coincident to the second-milling face. Once mounted, each first bisected-casing is positioned concentric to a corresponding second bisected-casing to form a single cylindrical casing for housing a rotor plug.
