How to B.E.R.P. an Explanation with Exercises
The B.E.R.P. Clamps firmly onto the open end of the receiver, with the mouthpiece removed. The clamp is designed to tighten around a round, hex or convex shaped opening. On some receivers which have an oversize ring at the opening, it may be necessary to push the clamp past that before tightening down. Most people prefer the B.E.R.P. To be lined up parallel to the receiver at the 'three o'clock' position. You may experiment with it in other positions to determine what is best for you. Once the B.E.R.P. Is firmly attached, you can then alternate easily between buzzing and playing your instrument by switching the mouthpiece.
THE RESISTANCE DIAL
The dial for the trumpet, horn and cornet B.E.R.P. Should be positioned below the holes and pushed up to cover however much of the holes creates the desired resistance. The dial on the B.E.R.P. For trombones, euphoniums and tuba 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 B.E.R.P. Should then be dialed similar to that on the instrument.
This exercise routine practiced on a daily basis will give you the many benefits of working with the B.E.R.P. Play slowly, using the top treble line for trumpet, cornet and horn and the bottom bass line for trombone, euphonium and tuba.
1. Clamp the B.E.R.P. Onto the receiver. Play the starting pitch on your instrument, then place the mouthpiece in the B.E.R.P. And buzz the exercise like a siren or glissando.
2. Buzz the exercise again, but this time play the notes from center to center and press the valves down or move the slide to the notes that you are playing. When playing on the B.E.R.P., practice making the beginning and ending pitch sound (resonate) the same. Correct sound production will result when the air leads the way, whether ascending or descending.
3. 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 B.E.R.P. And playing on your instrument. This will give you ear training benefits and strengthen the embouchure. This exercise can also be started on other open partials up and/or down. Practice with the same routine.
