You should get the book, "Welsh Traditional Music" by Phyllis Kinney (University of Wales Press, July 15 2011, ISBN-10: ? 070832357X) which is pretty much the best English language publication available. Also anything by Sally Harper, U. Bangor.

I'm very fond of the Welsh triban which compares three things with a clever or witty or moral connection. i.e. Three things easy to know: a man, an oak tree, and a day. The day turns (revolves/progresses), the tree is solid, and the man is two-faced. There are a lot from South East Wales - Mudcatter Dr Price is a good source for these. Ploughing with oxen continued well into the 19th century in Wales and tribannau were among the verses sung to the oxen as they worked to keep them happy. It was believed that oxen (as well as bees) were particularly wise and mystical and needed special treatment - a belief rooted in the dim and distant past. Young lads were hired - on audition - according to the breadth of their repertoire as they would walk backwards in front of the oxen, singing to them.

Get hold of Phyllis' book. You'll enjoy it.
