Having a real hard time creating an audible sound on the trumpet, however, I can play the trombone quite well with the larger mouthpiece. I even swaped out the trombone mouthpiece into the trumpet for a quick experiment and could blow wonderful notes. I am curently using a 5c mouthpiece in my trumpet. Should I go larger, say a 3c or 1.5? Any help/advice appreciated. Thanks.
