I have played many tunes by O'Carolan, including Carolan's Concerto. I don't think he wrote it at all. it simply lacks the magic. Carolan had a gift for mixing major and minor which very few composers have had.

It's like this: if someone told you that J.S. Bach wrote 'The Blue Danube,' you'd know he didn't. It's the same with Carolan's Concerto.

I tried playing it on the piano, and even after editing, it never really came together. And if you watch videos of harpers playing it, you can see the tension. They're killing themselves. Can you believe that a blind man produced something so hard to play?

It's a charming piece, but I think someone else wrote it.
