The first rule to bear in mind when choosing a mouthpiece is that there are no rules
A mouthpiece that works well for some players may not necessarily others.
We don’t need to try to play on a 1C just because the mouthpiece has a “1″ stamped on it!
And, there really is no such thing as a ‘high-note’ mouthpiece, although certain mouthpieces will *allow* freer/easier vibration in certain registers.
Blind testing is one way to find a new mouthpiece.
To do a blind test for a new mouthpiece, go through the following steps:
1. Lay all of the possible new mouthpiece candidates out on a table in front of you
2. Warm up on the mouthpiece you normally play on
3. Play a scale, arpeggio, or piece of music that is well within your comfortable range on your old mouthpiece
4. With your eyes closed (or get someone else to help you), remove your old mouthpiece and select a new mouthpiece to put in your horn
5. Play the same scale, arpeggio, or piece of music
6. Remove the mouthpiece, and try another, playing the same piece of music, scale, or arpeggio
7. Do this several times, until you get a feeling for the mouthpiece that you prefer
8. Bear in mind not only sound and range, but articulation and endurance
9. When you think you have the mouthpiece that works best for you, note down the size
10. Take a break, and start the blind test all over again
Go through these steps over several days.
What you will probably find is that you will quickly rule out more and more mouthpieces each day, leaving you with only 2 or 3 possible candidates after several days.
If it gets down to 2 different mouthpieces that you just can’t choose between, don’t worry. Both will almost certainly work for you. Make a decision, and stick with it.
Good luck!
