Ok, so first post ever, yay xD. Never mind. And I don't know where else to put this question, excuse my ignorance. Um, onto the question: So I have a Buffet E12 Bb clarinet that I got pretty recently, and I think I've gotten used to it, but......I just can't get that high b before the start of the altissimo range out. Like I can play practically every note except for that high b. I get to the b and nothing comes out but that grunting noise. I can somehow play the c above the b fine; and I kinda have to adjust my embouchure in different ways when I get to that b before it finally comes out. I'm preeeetty sure my clarinet isn't leaking or anything, but I guess that's always an option. I play size 3 Vandoren reed on a Vandoren B45 mouthpiece. So I'm wondering if it's just my technique/embouchure, the reed I use (I doubt it though, I have the same trouble on all my reeds), the mouthpiece I use, or the clarinet itself..... So any ideas or tips to help me out?
