This is one of the most beautiful tunes I play—but where I have got it from. Is it Irish?
Yes, it’s Irish!
It is a very nice tune — thanks for putting it up here! I just found it in my copy of O’Neill’s Dance Music of Ireland, so it is definitely Irish 🙂 .
Well, as it appears as "Lady Harriet Hope" in 18th century collections - and it seems that Lady Hope was the Lady of Hopetoun, by the Firth of Forth, I’d suggest that you don’t take O’Neill’s as gospel.
