There are several types of gold plating used in the electronics industry: [3] Soft, pure gold plating is used in the semiconductor industry. The gold layer is easily soldered and wire bonded. Its Knoop hardness ranges between 60 and 85. The plating baths have to be kept free of contamination. Soft, pure gold is deposited from special electrolytes.
Silver plating is common on all brass mouthpieces because it is cost-effective and good in terms of tone quality. It is also moderately germicidal. Silver plating is not as comfortable [citation needed] or as expensive as gold, but has properties and qualities that some feel facilitate certain styles of playing [dubious – discuss].

Single-reed instruments, capped double-reed instruments, and fipple flutes have mouthpieces while exposed double-reed instruments (apart from those using pirouettes) and open flutes do not.
Cornetts are made with a mouthpiece, similar to that on brass instruments, but very small. Unlike the brass mouthpieces, players don't press the instrument to the center of their mouths, as on a trumpet. [27] Rather the technique to produce sound is to hold the instrument to the side of the mouth, where the player's lips are thinner. [27]
