Maybe exotic isn't the right word, but I'm looking for kinds of music that are really out there and are usually only listened to by it's own culture.
I'm peruvian and some in peru would be Huayno or Ranchero.
I just want to learn some cool genres to look up on youtube and be able to play on guitar.
Make your own exotic music! Try these exotic scales:

You can get some pretty interesting sounds using these scales.
Appalachian. Unless you are a folklorist you probably don't listen to it.



Also they use a modal tonality like the guy a couple posts ago suggested, so even though it's American it is exotic.
