When you play a chromatic scale quickly, how do you change from the Bb to B? Whenever I try to play the scale fast, I can never change from Bb to B - when my fingerings go from a Bb to a B, no sound ever comes out. =( Any tips?

which B to Bflat?, if its over the break then practise, the other two theres a 'fork' finguring

Sorry, I was talking about the B-flat/B inside the treble clef staff

ya, that will come with practise, if you have your right hand already down in position that will help too

okay, thanks a lot!

If you mean the high notes then have your hand ready on G so when you start to go to B all you have to do is just put the first joint fingers down. If you mean the low than rember 1st than 2nd on the lower joint

.

you may also have a minor leak with your instrument. If you have B speaking problems especially going from the throat Bb to B.

also make sure that, if you are using your right pinky to play B that you are not shifting you 3rd ring finger a bit. Many students do that without knowing, which causes a leak which prevents the spatula key notes from speaking properly

here's a simply "at-home" leak test just to test your clarinet for possible leaks

other than that many players have that issue, and it just takes practice

Practise A-Bb slurred building speed up. Keep all RH fingers down on the A as well as 2nd & 3rd LH fingers down. Pracise rolling the LH pointer from A key to 1st hole (F#). When doing this, keep LH pointer on the bottom of A key. Now do the same going Bb to B.
