Scale of the Day: E Flat Aeolian mapped to the Cube-root-of-2

EFlatAeolianMappedToTheCubeRootOf2

The E Flat Aeolian mapped to the Cube-root-of-2 Scale. There's something subversive about compressing all the intervals of the traditional "harmonic minor" scale into the span of an equal tempered major third. Conceptually, there's the contrast of squeezing minor into major. Cognitively, however, the "tonality" of major/minor doesn't really carry over as one ends up with a scale with several sixth-tones. The compositional/improvisational challenge is to treat each 400-cent "major third" as a harmonic equivalence.
