The E Flat Aeolian diminished 4 mapped to the 3/2 Scale. Again, with the altered nature of the diminished fourth degree this scale takes on its harmonic qualities from the uneven distribution of pitches over the span of the 3/2 (just perfect fifth). Of particular interest is the tight 58.50 cents between the third and fourth degrees compared to the wide 175.48 cents between the fourth and fifth degrees.
