The Denis Wick Tone Boosters are designed to fit most mouthpieces to increase the mass or weight at the cup of the mouthpiece. This allows the player to get a bit more energy into the horn without additional effort. They also help stabilize the mouthpiece to make it easier to "lock in" to the notes.
