Silver plating is almost always used on brass mouthpieces because it does not cost too much money and a silver-plated mouthpiece helps a player make a pretty good sound. Silver plating is not as expensive as gold, but it is sometimes very important to have if a player plays a certain way. Silver-plate gives a clearer sound than gold and is good for styles of playing that need a lot of volume. Also, silver needs to be cleaned more often because it smudges easily.
