First question is how would you go about double tonguing on the bassoon.
Second question is there any other fingering out there for going from A3 to G#3 when it's staccato and quick.

I'm playing Mendelssohn's Italian Symphony in a week and those are the only two trouble spots that I've come across. I've tried single tonguing in the one rehearsal that I've had before the Holidays and my jaw was never the same.
