One problem in tuba performance is the use of a mute for the tuba. With no research existing a tubist has two methods with which to gain knowledge about mutes; he can learn by trial and error or he can consult a tubist having more experience with the problem. A source is needed to aid a tubist in locating information on mutes for tuba. By learning more about the uses of mutes, the availability of mutes, and the effects of mutes on tuba performance, a tubist will be better equipped to select a mute for personal use. This study is designed to provide, objectively, that knowledge to the tubist.
