BERP = Buzz Extension and Resistance Piece
HOW TO BERP ?
Clamp The Berp onto the receiver. Play the starting pitch on your instrument, then place the mouthpiece in The Berp and buzz the exercise like a sirene or glissando.
Buzz the exercise again, but this time center each pitch and press your instrument valves down or move the slide to the notes that you are playing. When you play The Berp, practice to make the beginning and ending pitch sound (resonate) the same. Correct sound production will result when the air leads the way, whether ascending or descending.
Finally, play the exercise on your instrument with the same energy you used to make a consistent buzz. The embouchure should feel more relaxed than when buzzing in order to get a free, resonating sound. Always alternate between the berp and playing your instrument, to gain ear training benefits and strengthen your embouchure.
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.
