Is there a baritone mute

Answer 1

There is a such thing as a baritone mute. It is rare to find them in any store and if you see someone using one, they have usually constructed it themselves. Most mutes for baritone look like a very large practice mute for Trumpet, and are rarely used by any baritone players. Baritones with curved bells(e.g. bell front concert horn) make it dificult to use mutes, as well as the fact that most Baritone/Euphonium have different bell radii, making a standard mute hard to make.
