please give me advise I have big lips and teeth protruding which size I can use from mouspeice.

I witing for replay .

you`ve either got to work with your handicaps or from what you`ve said you might be a good baritone player. same fingerings as trumpets just lower and bigger mouthpiece. better for bigger lips

Many great trumpet player had big lips. I really don`t have thin lips (not big either)... but I`d say it isn`t a problem. Bigger mouthpiece isn`t necessarly the solution. Depending where you live, you may have the opportunity to go to a musci shop^and try different mouthpiece... this way, you`ll know what works for you!
