A wonderful instrument! I don't have an (Irish) cromatic flute, but I do have a fine Irish "pennywhistle" in D. It's easy to play, but hard to play well (as with so many things in life...). I've used it on several of my "in-house" productions, such as
Far Away which you can download
here. You can hear the flute starting at 4:26 (but it's only a very short passage, I've used it more extensively in other pieces).
When I have time (unfortunately rarely these days
) I practise on the instrument, and I plan on buying some more (advanced) Irish flutes in the future. The one I've got now, was a Christmas-present from my sister, brought home from Ireland. Best present ever!
Here is a website dedicated to the Irish flute.
