so i was wondering what the ‘proper’ embouchure was for playing the whistle. i have tried a few (curling in bottom lip a little, not curling it in, curling top lip, teeth on top of fipple, no teeth, etc…) and i was just wondering if there is an accepted ‘proper’ embouchure and if so, what is it?
Well, being the highly opinionated person that I am… NOT! 
… just think about the fact that it is a whistle, nothing I have found is really an ‘absolute’ of any kind, nor do I believe anyone for the most part would really combat each other on the subject…
Plenty of suggestions, but absolutes? Like I said, it’s a whistle… any improvisation is pretty much encouraged!
Oh yeah, there is probably one absolute… having FUN while playing. 
Take care,
John
having fun while playing.
woot, finally something i have down to a science 
Personally, I try to keep it away from my teeth, more to save my teeth than anything else. But the size of the inside of your mouth makes a bit of a difference in the sound that comes out. Experiment to get the sound you want. Drop your jaw and sound the note, then slowly change that space and see what happens.
The angle of the whistle in your mouth also makes a difference, and you can bend a note a little by changing the angle. I don’t think there is a right or wrong (other than NOT PLAYING IN A MOVING CAR!) but whether you can consistently get the sound you want.
Hi Damien,
Just tried a few different whistles to see what I actually do!
I just relax my mouth, no puckering, no curling in of lips, place the end of the fipple between my lips, and blow. No teeth touching the fipple, that’s a nono I think; and when playing the upper register I tense my lower jaw a little. When tonguing, I don’t ltouch the fipple at all with my tongue, just block the airflow slightly.
Some people hold the whistle to one side of the mouth, or put their head one side. This can help you hear your own playing in a noisy environment, and to hear the sound that other people are getting from your whistle.
I think my advice would be to be relaxed, try things out, and do what works for you. Whistle is the most comfortable instrument I know to play (compared with fiddle, mandolin, guitar, clarinet); it doesn’t require bodily contortions, or calluses on the fingers. You can grow your nails long or not, it won’t affect yur playing.
As far as I know, there isn’t a specific embouchure for the whistle (not like there would be for, say, flute or saxophone or trumpet)… I’d say just play the way you are most comfortable. Comfort is a must, and when you are comfortable while playing, it takes the risk of aches/pains down, b/c your body naturally wants to align itself in the most anatomically correct manner.
