Would an advanced clarinet player be so kind as to look here at this fingering chart:

If you pootle off to the bottm, you'll see a series of very very high notes. I have a small problem with them - I'm getting concert pitch on ALL of them - if I try to play a clarinet G, I'm getting a clarinet A. Admittedly that's (I believe) the highest note a clarinet can get, and I'm a little proud of myself for getting it (and having it sound nice) but it's not the note I want to be playing it. Help!
