I so want to learn how they dance like that. I hear it is a little like belly dancing. Should we come up with lyrics to a song for them?
Oh, gotchya. I thought you meant the tiganza music.
The following comment is based on knowledge from the end(ish) of Book 4, The Shadow Rising:
I personally think the song they're looking for is the one Rand sees when he goes through the glass columns in Rhuidean, with Someshta dancing through the fields and all of the Da'shain Aiel and Ogier joining in to help the fields grow. I would love it for the Tuatha'an and the Aiel to reconcile after the Wise Ones/clan cheifs meet with the Mahdi and teach them the song they heard in their visions. I doubt it would be the same without a Nym, though. The full song may truly be lost forever.
If the above theory is correct, the song would have a nature-based theme.
