im a student and i play with a shilke 15 and sometimes i feel that this mouthpiece is a too big for me.. i like the big sound of this shilke 15 but in the upper register is very difficult.. i try a yamaha 11b4 and is easy to play upper register but i dont like the sound.. so my question is ..
should i try shilke 14 ou 13? or
should i stay with this shilke 15 and continue practicing until can get better upper register with it?
I think playing with a small mouthpiece dont develope the embouchure.. But play with a too big mouthpiece is a problem too?
