Thank you so much for the tips. I had a feeling it may not work on the NAF. I guess I'll have to use my son's recorder to get my craving met!
Flutetree.com has sakura....It sounds much better when played on recorder...My 10 year old daughter played it on recorder for a school concert, and when she tried to play it on the NAF, it just didn't go well. Good luck, it is a beautiful piece.
