The baritone mute now completes the range of straight mutes for all the brass band instruments. The tuba mute has more clarity and is superior in all registers than any other so far developed.

Denis Wick practice mutes are perhaps the best teaching aid ever invented. Not only do they fulfil the need for the IN TUNE painless practice, so essential in the development of every young player and an indispensible ‘hotel mute’ for the professional, but they also make possible an enormous improvement in tone quality using the entire vital capacity as a vibrating air column by opening the throat spaces through playing loudly in the low register. They are a fraction of cost of the electronic practice mutes now available, which do not develop the sound in the same way.
