5L 7s, also called p-chromatic, is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 5 large steps and 7 small steps, repeating every octave. 5L 7s is a child scale of 5L 2s, expanding it by 5 tones. Generators that produce this scale range from 700 ¢ to 720 ¢, or from 480 ¢ to 500 ¢. Temperaments that support this scale include Pythagorean, schismic (such as Helmholtz and Garibaldi), and superpyth, with the Pythagorean and schismatic scales in particular being proper. Scales of this form are characterized by having a small step (or diatonic semitone) that is smaller than the chroma (or chromatic semitone).

Modes

The modes are named by Eliora after Chinese zodiac animals. 5L 7s is the opposite mos to 7L 5s, named after a Western concept, Gregorian months, therefore this mos scale has Eastern nomenclature.
