I love to play the tin whistle. Very inexpensive. The "Generation" brand is what I have for the six whistles I currently have. The downside to these Generation whistles is that the mouthpieces are glued on and the band leader I was working with said you need to adjust the mouthpiece when it goes out of tune. He said a way to tune it is to get a juice container of ice water and put the whistle in it almost to the mouthpiece, but don't let the mouthpiece touch the ice water. It will eventually shrink the metal a little bit. Then you slowly and gently adjust the mouthpiece when you take it out. I've seen youtube videos of people stating to use hot or warm water, though. I should note that the whistles I have for the various keys are barely $15. I was however looking for a Key of A whistle and the store had to order one in, I think it was a different brand and it was around $40 I believe.
