I started this thread on the other site and thought it would be worth repeating here too.
I've noticed that posters usually pop up with the same pat answers to various questions. The purpose of this thread, then, is to create a listing of one-liners that new posters can read and digest upon. Also, it will save responders from having to type them out every single time. Feel free to add your own.
New TM'ers: pick the one that applies to your situation.
1. Find a local, highly-qualified teacher and take regular lessons.
2. Don't focus so much on equipement -- just worry about making music.
3. Use more air. (That'll work for anything, including how to keep Arban's open on a wire stand.)
4. Listen to recordings for hours each day in order to have a proper sound concept. That will fix any problems you have.
5. You really need to try a mouthpiece before you buy it. We can't tell you which piece to buy because mpcs work differently for everybody; however, the fine folks at (Mouthpiece Company Name Goes Here) can. Just fill out their questionaire or give them a call.
6. You really need to try the horn before you buy it. Horns play differently for different people.
7. Even though you asked about _________ brand, you should really try _______, ________, __________, and ______________ (even though you didn't ask about them).
8. Just practice more.
9. Don't think about what you're doing. You'll absolutely 100% get paralysis by analysis.
10. If you're looking for a student trumpet, or are a comebacker, the required setup for you is an Olds Ambassador with GR Mouthpiece.
