12L 7s, also called m-enharmonic, is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 12 large steps and 7 small steps, repeating every octave. 12L 7s is a grandchild scale of 5L 2s, expanding it by 12 tones. Generators that produce this scale range from 694.7¢ to 700¢, or from 500¢ to 505.3¢. Temperaments associated with this scale include meantone, as the meantone enharmonic scale.
