The E Flat 5, 3 Mixolydian Scale. The conventional 5-limit just intonation configuration of this scale features the 4/3 perfect fourth and 16/9 minor seventh as the two utonal intervals.
The A Flat Pythagorean Construct No. 1, Lydian Mode - in Square-root-of-2-space Scale. The 3 (Pythagorean systems are 3-limit just) is divided by the square-root-of-2 until one arrives at an interval between the root and the square-root-of-2 "tritone."
The intervallic content of the E Phythagorean Construct No. 1 - Lydian Mode - Scale. As there are only two notes (and a harmonically equivalent octave), this scale has a small set of intervals.
The A Flat Pythagorean Construct no. 1 - Lydian Inversion - Scale. The inversion of the otonal 3/2 perfect fifth becoming the utonal 4/3 perfect fourth in this particular case.
The G Dorian mapped to the Square-root-of-2 1% wide Scale. Dorian symmetry in a harmonic landscape where the 606-cent "tritone" serves as the interval of harmonic equivalence.
