7L 15s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 7 large steps and 15 small steps, repeating every octave. 7L 15s is a grandchild scale of 7L 1s, expanding it by 14 tones. Generators that produce this scale range from 163.6 ¢ to 171.4 ¢, or from 1028.6 ¢ to 1036.4 ¢. It is the enharmonic scale of Coendou temperament.
