Scale of the Day: E Flat Pythagorean Lydian no 5 mapped to the Square-root-of-2
The E Flat Pythagorean Lydian no 5 mapped to the Square-root-of-2 Scale. A Pythagorean refinement of the quarter-tone scale with the subtracted fifth degree allowing for 6-pitches per 600-cents (the interval of harmonic equivalence). I could have represented the frequency ratio of the square-root-of-(81/64) as the more conventional 9/8 Pythagorean whole-tone (9/8 being the square root of 81/64). But the visual representation of squaring all the standard otonal Pythagorean intervals is more appealing.
