This is exactly what DOESN'T happen. If we were pouring water through the mouthpiece, you would be right, but music is like AC not DC. That means boring out the throat does not give you a freer blow, but DOES reduce the efficiency of the mouthpiece/horn and makes the slotting fuzzier! The throat and the backbore need to be optimized and you ALWAYS have to trade off characteristics when modifying a mouthpiece!
The less air the better the sound!. Before anyone jumps down my throat, let me explain: a clear sound efficiently played requires a small but strong aperature. Less air goes through the hole because the horn is doing the work, not brute force playing. We still have to take a deep breath to put a large volume of air behind the lips. That air just does not disappear when playing correctly! Your air should also not be rammed through the mp!

I am not looking for a "cheater" mouthpiece, I am looking for something that will give me room to grow.
I'll have to go to the store to try out different mouthpieces... none of my friends have anything I want to try...a bunch of tiny shilkes or Bach 7Cs...
I play on a very deep cup now...but I think I am looking for something shallower. I need flexibility, response, and clarity. I may end up on a D cup, but I'll definitely try the 6BM...the 6 rim is what I was looking at anyway...
I would also like to look at some V pieces... I am not very knowledgable about anything oddball (strange, considering my equipment), so does anyone know of any manufacturers who make V pieces that I could find at a local Swicegood?
Also, has anyone ever seen a chart or table or something that gives the characteristics of each type of mouthpiece, and their equivalent to other brands? I have trouble converting American standard measurement to metric, much less converting the different labeling systems... |
The Kanstul Comparator and there is also a table at the Monette site. The information will not really help you solve your problem, only playing will.
