I have just discovered that at the start of practise my tone sounds fine and I'm thinking to myself, this reed sounds good and after about half an hour or so it deteriorates and starts sounding that there is a lot of air running past the reed and making a funny noise it eventually (or me) starts to squeak. Today it happened again so I happened to change the reed back to one I played yesterday (one that I discarded for the same reason) and it sounded wonderful....Grrr.
It seems that I generate a lot of moisture when I play, could that be it?? and how do you go about curing it. I have my grade one shortly (still waiting for the date) and don't want it to happen in the exam.
HELP
