Scale of the Day: E Flat Pythagorean Mixolydian no 4
The E Flat Pythagorean Mixolydian no 4 Scale. This is the 3-limit (Pythagorean) just intonation version of this subtractive scale. The 32/27 minor third appears between the 81/64 and 3/2 where the missing 4/3 perfect fourth would have been. Without that fourth degree the 16/9 becomes the only utonal member of this particular set - a property normally associated with Ionian scales. But the 1024/729 diminished fifth between the 81/64 and the 16/9 give this scale its unmistakable Mixolydian flavor.
