@KitRedgrave Pentatonic scales in general are pretty great for that, regardless of what kind~ Enough tones to sound interesting, not enough for them to clash horribly unless you pick a -really- dissonant scale for them.
Of course, you can go practically anywhere with the scale itself... experimenting with stuff outside 12-TET may be worthwhile, too.
@Thaminga that was my line of thinking :3 there's a lot of xenharmonic systems out there
@KitRedgrave so of course I immediately worked this idea out in greater detail
@Thaminga this really makes me wish i had a midi keyboard right now so i could play around with these
