My mouthpiece isn't playing too well for me. I have a wooden LeBlanc clarinet, and a plastic mouthpiece with a chamber that is too large. Any suggestions on a new mouthpiece?

Beginners/Intermediate
I would recommend
David Hite Premier (around $30)
Pyne Clear Plastic (around $40 or 50)
Vandoren B45 (50s)
Intermediate/Advanced
Vandoren 5RV, M13, and M14 i think
Pyne (expensive)
Genussa (lives in ocean city maryland)
Gregory Smith (too much money)
All the advanced mouthpieces are above $75 but if you find the right one than its worth it. I would find a place that would send you several at a time so that you can try them out like Woodwindandbrasswind.com and Weiner Music. All mouthpieces are different (EVEN the same make and models feel different) I play on the Genussa but I tried the David Hite and Pyne and it was great playing. Good Luck
