I am a 2 decade comebacker. It feels great to play again. Seems like I retained most of my trumpet muscles however I do have an issue. When I pick up the turmpet fresh in a day my range is very good. I can pop out some very good double E's, F's, and some G's. But I deteriorate very quickly. My question is what is most likely? Is it more likely that I am applying too much pressure and cutting off my circulation in my lips or is it the student trumpet that is affecting my range. BTW, I never hit double E's F's and G's in my life until now. I got a Shew lead trumpet mouthpiece and I lucked out.
