After retiring from professional playing, I have started giving lessons to High School kids. I have one student who is 11, but most are form 13 to 16 years old. I am about to make a controversial statement and I would like anyone who genuinely disagrees with me to tell me why.
1) First of all, most of these kids have their lips stretched to thinly on the mouthpiece and the stretch is from side to side. I believe this is absolutely wrong. Thicker lips vibrate much easier and take less air to get more sound.
2) I think this general practice of just giving a kid a 3c or a 7c is just plain dumb. I personally play on a shallow cup Lynnflex (Stomvi) mouthpiece which I agree is too small to let starter students play. But when you think about it, kids have smaller lungs, smaller chops, smaller everything, so I think a smaller cup like a Schilke 12A4a or 10A4a is a better place to start. When I have done symphony work, I have always worked on a 1 or 2 C Bach and can switch with little problems. I think we start these kids on too deep a cup and to large of a diameter and they get frustrated. We all know what happens then. Does anyone out there have any comments. Thanks!
When in doubt just blow harder.
