I'm a hobby guitarist and I'm looking to switch things up by playing another instrument for a little bit. So I'm looking into buying a Native American style flute ('NASF') because of the timbre and apparent playability.
But these flutes are pentatonic instruments, are they not?
Considering guitars are chromatic instruments, any guitar should theoretically be able to hit the same notes as a NASF and will be able to 'play along' just fine. But what key makes playing along easiest?
I've seen one manufacturer reference that the key of G is most popular. Should I 'just' get my instrument in that?
Note: A local store sells NASFs in A (shortest), G (middle size) and F# (longest).
