The present invention is a keyboard bag for a percussion keyboard instrument (vibraphone, marimba, xylophone, metallophone, glockenspiel, or the like) for safe operation and transportation of the keyboard, which is the most essential and expensive component of instruments of this class. Unlike known bags for a similar purpose, this bag uses special internal bar tabs which, when placed on the keyboard, are inserted into the gaps between adjacent bars, thus separating them and preventing them from coming into mutual contact, under various operating and transporting conditions. This bag helps to protect the keyboard of the instrument from unwanted physical impact and damage and provides for more convenient and efficient mounting and unmounting of the keyboard during assembly and disassembly of the instrument.

A bridge for a stringed musical instrument is provided. The bridge is machined solid from various metals, selected for their metallurgic and sonorous qualities.
