Lets Talk Native American Flutes.My knowledge is very limited, but I will try and start things out.
There seams to be two types, a five hole Diatonic and six 6 hole Chromatic flute. A Chromatic can become a Diatonic flute by covering the last hole.
I was told, by a flute maker, Tim Minton, of Lindsy OK, that the true Native Flute is a Diatonic flute but "The White man wants to play Amazing Grace so he needs a Chromatic flute". How did he know I wanted to place Amazing Grace?
Tom Minto makes a "Reed Flute" that really sings. That little flute is my favorite.
Other Flute makers are Paul Thompson of Albuquerque NM, George Taylor of Las Vagas. , and Funmaker (Think That's his name) of Minnesota.
I have found that some are harder to play than others, I'm not sure why, they seam to have a mind of there own.
The sound of any of them is truly magic, I can quite down the most unruly children with a flute. I wish I would have known this when my children were young.
Some place I have a little song book for a Diatonic flute, If anyone is interested I'll try and dig it out.
