B flat clarinet high G, like high high G the one above the staff with the leger lines, that is with the chromatic fingering being all sharp, flat and unstable, and the alternate fingering for it is in tune for me but it drives my hand crazy, I need to practise running up and down to it
On my Bb clarinet-High E (on the staff). I recently played a trio with my friends and had high e's all over the place, and I couldn't stop squeaking when I played them. I'm pretty sure it's my clarinet though. It's kind of old. It needs a new mouthpiece. And there is a pad that kept falling out.
On my Bass clarinet-High G and up. They are just mean.
Throat Bb. That is the most horrible sounding note to me. BTW...which alternate fingering are you using on High G? is it TR|1x3|1x3|Eb by chance? I LOVE that fingering for G. But if you over blow a B (one line one space above the staff) you get a G also . I use that fingering quite frequently in Poulenc's Sonata for Clarinet. Most notably in Mvt. 3, Rehearsal Number 3, Measure 4. I use it because it is SOOO easy to use that fingering and go to E right after it quickly.
I HATE top line of the staff F# on the Bb clarinet! It sounds horrible! Whenever I play it and the D above the staff, I get a feeling that I have a coin in my mouth! YUCK! They are usually very sharp for me.
I really hate playing c sharp too! At the beginning of this year it would come out really squeaky. But now it isn't so hard anymore. (occassional squeaks every now and then)
