Keyboard Phenomena

This small strip is merely cosmetic and serves to cover the gap between the stretcher and the near edge of the plate. It is secured by a handful of screws. It became the source of an intense buzzing recently, and the solution to correct the problem was the introduction of a strip of felt on the vertical face that I cut to have a nice straight edge. It looks great after re-installing. The bottom face was already felted by the factory.
