Hey all, I am a Sophomore and High School and my main axe is Tuba. I have been playing for about 5 years now, and I am really loving Tuba. Since last year, I have been wanting to learn trumpet. Last year I bought a trumpet, and started to practice. But I have trouble when I practice, since I am coming from mouthpieces that are completely different in size, and I tend to see my lips swell on the trumpet, just practicing for a small bit. If you guys could give some tips for me that would be great! Thanks so much for your help!
