Hey Greg,
I’ve just got to the first exercise at Andante (C adding Eb then Ab) and it has, coupled with playing outside of the windworks practice, made me more aware that my bottom lip gradually slips between my teeth and eventually blocks my air stream. I’m definitely not clamping or forcing the air but the whole thing just shuts off. Could it be a jaw thing? If so any specific things that might help. I have been following the largo stage stuff carefully and it’s the only thing I can’t get my head around.
Thanks Thom
