Lisa, I wonder if your teacher was also a tale teller? (or a leg puller) There are some songs in circulation that either tell the NA point of view, or have tunes that come close to Indian chants, but I have not run into any information on fiddle crossover tunes. Just offhand, I wouldn't think that NA tune structures would lend themselves to fiddle. Possible some of Carlos Nakai might translate.
Anyone?
Blessings
