Wanna try some scales with naturally occuring quarter-steps?

Try some of these out (scroll down a bit). Though they're meant to be played on an Oud (a fretless cousin of the guitar), but a lot of the notes can be reached through pre-bending of notes or by using a slide. Try them out next time you're jamming middle-eastern style.
