make sure none collected in the mouthpiece or in the neck, and also make sure that your reed isnt like hugely off the mouthpiece and your lips (EMBROCHURE) fully seals around the mouthpiece...
Good LUCk

Yes, I had this exact problem on my Bb clarinet 2 weeks before a performance! I sounded airy and raspy but I passed it off as a bad reed or bad reed positioning! However, when I performed what I was going to play to my teacher, she said my mouth hadn't sealed around the mouthpiece, and suddenly I realized that was what it was!
Anyway, you just need to play a few pieces every day just concentrating on keeping your embouchure sealed, then it should start to come naturally!
If not, i'm sure someone can help you!
Happy playing!
