12L 8s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 12 large steps and 8 small steps, with a period of 3 large steps and 2 small steps that repeats every 300.0¢, or 4 times every octave. 12L 8s is a grandchild scale of 4L 4s, expanding it by 12 tones. Generators that produce this scale range from 180¢ to 200¢, or from 100¢ to 120¢.
