13L 10s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 13 large steps and 10 small steps, repeating every octave. 13L 10s is a grandchild scale of 3L 7s, expanding it by 13 tones. Generators that produce this scale range from 365.2 ¢ to 369.2 ¢, or from 830.8 ¢ to 834.8 ¢. The 13L 10s MOS scale has its large steps split 2-1-1-2-1-1-2-1-1-1 between the small steps. It is the major quartertone scale of 3L 7s (sephiroid) and the quartertone scale of unidec temperament.
