I've played trumpet in band for the last 2 years after being on baritone for 2. For band camp and all district stuff I do baritone because it's the one I'm most comfortable with. I play trumpet because I'm the only person in our highschool band who knows how. Someone (who isn't in band) said that I might be better on baritone because of the bigger mouthpiece (I have big lips) and I was wondering how true it could be. Right now I play on a 3C because it came with an old trumpet passed down from my mom but I started trumpet with 7C or 7A I can't remember lol. Anyways do y'all think I should try a larger mouthpiece?
