I just got a whistle and am In Love With It, but I can’t play it. Any reccomended books or websites for starters for me? 
www.fingertrip.net was my favorite.
Depends on if you’ve played instruments befor or not, though. That’s not really a teaching site.
Try Bill Och’s Whistle Tudor book. I got mine at The Whistle Shop. It is for both beginners who have never played any instrument or those who already read music. The level is broad enough to appeal to all. Plus, the CD that comes with it is great to give you the “feel” for the tunes.
thanks so far! keep posting! I need as many ideas as I can get 
Easily fixed. Just go visit Brother Steve…
