okay my band director is sending in my old aristocrat to get fixed and i currently have just a mouthpiece. its pretty depressing going from a trumpet to this little mouthpiece. during band i use his TR300, but at home i just have my mouthpiece. this is probably going to be the situation for at least a week. does anybody have any good exercises i can use that could improve my playing. with my horn i am pretty accomplished and i can scream pretty high, but i was hoping maybe with a mouthpiece i can not only improve my lower note tone, which isnt superior compared to how it could be and strengthen my embouchere. does anybody here at trumpetmaster know of anyway i can do this with only a mouthpiece?
