The buzz extension and resistance piece, better known as The Berp, helps you develop proper breath support by blowing into resistance, letting you buzz your mouthpiece while you hold your instrument in the regular playing position. The Berp also lets you press your instruments valves or move the slide to match the pitches youre buzzing, so you gain ear-training benefits through reinforcing the connection between buzzing the mouthpiece and playing. The clamp: The Berp clamp fits firmly onto the open end of the instruments receiver with the mouthpiece removed. Its designed to tighten around a round, hex, or convex-shaped opening. Once The Berp is firmly attached, you can easily alternate between buzzing and playing your instrument by switching the mouthpiece. The resistance dial: The dial for the trumpet, horn, and cornet Berp should be positioned below the holes and pushed up to partially cover them to create the desired resistance. The dial on The Berp for trombones, euphoniums, and tubas should be positioned above the holes and lowered to create the desired resistance. Beginners usually have a better chance of getting a good buzz with slightly more resistance. Once a good buzz is achieved, resistance on The Berp should be dialed similarly to that of the instrument.
