I recenlty was discussing mouthpieces with my trumpet professor and found that his view on mouthpieces was one that I had never heard. He basically said that a shallow mouthpiece is not a cheater piece. It is actually more difficult to hit a note right in the middle of it on a shallow mouthpiece. He went on to say that one reason orchestral players play on the deeper mouthpieces is because the target for the note is much larger than on a mouthpiece with a shallower cup. Of course for tonal reasons he wants me to play a deeper cup for legit stuff. Darn no playing my jury on my GR 66Z** I just had never heard it put that way before. Just thought I would share this little nugget of info.
