Hi Mudguard,

All whistle players suffer from this problem. I myself prefer not to shake the whistle out.. unless of course there is a bad bodhran player downwind! I usually blow through the mouthpiece with the sound hole covered. There are lots of tin whistle sites on the web if you are interested, mine is The whistle workshop There is also a links page to other whistle sites.

Happy Noodlin'

Dave.
