Most students, youth or adults, learn the lovely welsh "jigs" which are actually clog dances from Wales. I was alerted to this fantastic video via the Harplist. It is from the Welsh version of the National Film Board, and dates from 1959.
You'll recognize the Pant Corlan and the Welsh chord pattern, and get to see the harp playing and the dancing happening at the same! Sooooooo great!
If you've only done Pwt-ar-abys and not the tune in the video, just email me or leave a comment below and I'll send you the music. Left hand is the same as you've learned. (end of Harpstart Bk 1 if you are confused :)
