Owned by Robert Gatliff, a long time enthusiast and explorer of the Native American Fllute, this site is full of resources for anyone wanting to know more.
Robert has included several songs in tablature format ( including the flute picture tablature) as well as listed several scales for people who want to break away
from playing the basic scale of the flute. I use this site on a regular basis with my flute circle and my flute students.
You can learn a little about the history of the flute and find some tips for playing aS well.
