These tunings are not your more common Native American Style tuning. They can be:
Hijaz or Arabian tuning gives the mysterious sound of a snake charmer, with Middle Eastern tones.
Aeolian tuning has a haunting sound of Eastern Europe and Asia minor (seven-note minor scale)
Anasazi tuning, like a Celtic goddess singing a ballad (major NA scale)
432 HZ the natural and fundamental electromagnetic “beat” of Earth.
- Or Akebono, Kavaal or Phrygian.
*Keep in mind that different scales change the hole size and spacing, so you may see large holes next to small holes with varied finger spread.
