Simply put, the Berp is the most efficient tool you can use 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 or move their slide 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 concept.
