I've got a Native American-type flute built into a 5-foot cedar walking staff. (couldn't resist it; it followed me home), and it's tuned to some kind of pentatonic scale. Anything you play on it can probably be accompanied with one chord, or a drone.

So, is this modal or related to modal? Or is it that a minor pentatonic scale is just an elaborate 7th chord? Or is that the same thing?
