So I'm planning on going from 3c to 1c mouthpiece. My mom is getting it next week, but I'm not too sure about making the switch now. First ill say my reason for switch. Honestly, I'm not doing it for instant wonders to range or whatever. I just feel a bigger mouthpiece would suit my mouth. My mouth isn't ridiculously huge, but I'm black, I think that says enough.... I really don't think the 3c is really right for me. Going from the 5c to 3c really helped alot of things, but I still feel that there's still issues like it's not wide enough in rim to fit both my lips enough and I know another trumpet player whose teacher told him he had big lips and should get a bigger mouthpiece. So he went and got a 1c mouthpiece and said it's a better fit after getting used to it. Now my worries about switching is that I'm a lead trumpet in a YJO im in and 1st trumpet at school, play 1st in school jazz band on songs the other trumpets cant play, and have auditions coming up. Thing is, I dont have concerts or any significant audition for 5 weeks. Is this a good time to switch? I wont have a very large amount of time to get used to my mouthpiece really till the end of the year, but that's too late. I think I might be damaging my mouth because my mouthpiece rim, along with the pressure ive been working on getting rid off. So I'm wondering if I could avoid the embrochure issues from the switch by slurring, pencil exercise, and buzzing on the mouthpiece alot. I really wanna switch next week. What would you all say. Is 5 weeks enough time if I do those embrochure exeercises? I really really wanna switch mouthpieces next week. I even got the money. But I want advice. My trumpet teacher said that he'd let me try his 1c mouthpiece for awhile before I buy next week too. Good idea, or no?
