Created by Mario Guarneri, the BERP (Buzz Extension Resistance Piece) grew out of the concept of mouthpiece buzzing which has been used for many years as a teaching technique for brass players. Mario combined buzzing with learning to blow into resistance, which in fact happens when you play the instrument, and moving the valves of the trumpet. This helps the player to become more aware of the undesirable creation of resistance in your body, and thus avoid it by using proper breath support.

The Berp is an efficient tool to help you become a better brass player. It is designed to allow you to buzz your mouthpiece while holding the instrument in the regular playing position. The player can then press the valves to match the pitches they are buzzing. The connection is made between buzzing the mouthpiece and playing the instrument in a very real way. The benefits of buzzing have now been increased and expanded considerably with the BERP.

The BERP features adjustable resistance dial slides over four holes to let you tune the BERP to any resistance you want. Beginners can set it to the resistance that matches their ability.

The adjustable clamp fits around the receiver opening of any brand or model of instrument.

Side-by-side design lets you switch between playing and buzzing instantly. You can efficiently work out passages through playing and buzzing more easily.

With the BERP you can:

• Maximize sound production and ear training
• Instantly switch between playing and buzzing
• Warm up quietly
• Build embouchure, endurance and range
• Adjust resistance to fit your preference
