Questions Regarding Sunreed's NA Style Flutes

What is difference between Sunreed's "Traditional" key Native American style flutes...G and F?

What is the difference between the 5 and 6 hole Native American Flutes?

G is the most popular key, our favorite, and one we most often recommend. The F is a little deeper if you prefer that. The 5 hole pentatonic is the most traditional method of playing, though the 6 hole pentatonic has gained immensely in popularity. While players claim the 6 hole pentatonic has "more notes" available, that is a misunderstanding of the methodology of playing. Our 6 hole, however, is a major diatonic scale (do, re mi) and more adept for those wishing to play contemporary/western style music.
