There are two styles of flutes, the Plains Flute & the Woodlands flute. The difference is very subtle and it has to do with the way the air flows through the bird. In the Plains flute the air channel is cut into the bird & in the Woodland flutes the air way is cut into the body of the flute under the bird. There is very little actual documented history when it comes to different designs associated with specific tribes. The wording of these two styles describes the areas were they were made – Plains, in the grass lands – Woodlands, in wooded regions such as mountains, etc.
We do know that the flutes made from river cane were primarily created by Natives in the South. We make our flutes the Plains style.
