7L 8s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 7 large steps and 8 small steps, repeating every octave. 7L 8s is a child scale of 7L 1s, expanding it by 7 tones. Generators that produce this scale range from 160¢ to 171.4¢, or from 1028.6¢ to 1040¢. It is notable for supporting porcupine, of the porcupine family.
