I played trumpet in junior high and I loved the instrument. Unfortunately, some disagreements with the a band instructor didn't do much for my motivation (that, and I was bored with the class). Funnily enough, it was Contrane that renewed my interest in the trumpet. I picked up the instrument the other day expecting to start where I left off (yes, foolish in retrospect). I picked up the fingerings quick enough, but I'm having some real trouble with my embouchure. I can run through the scales after warming up, but there's some struggling; especially on the low end. The mouthpiece is 7C, but it feels small. Maybe it's the lack of practice, but it's actually leaving a red mark (not the most attractive thing, if nothing else). I'd like, if at all possible, to bring myself up to speed. Any tips?
