These fingering charts work for Tsunami Flutes. Not all Native Style flutes will play like a Tsunami Flute. But a Tsunami Flute will play like most Native Style 5 and 6 hole flutes.
Some flute makers will try to tell you this is impossible. Perhaps it is impossible on their flutes, or perhaps they want to try and sell you three flutes when only one Tsunami Flute is all it takes to play three scales.
To play a sliding "blues" note or intervals between any note, just roll the finger off of the hole. This is called bending a note. Tsunami Flutes bend notes to make a smooth transition from one note to the next.
