6L 18s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 6 large steps and 18 small steps, with a period of 1 large step and 3 small steps that repeats every 200.0¢, or 6 times every octave. 6L 18s is a grandchild scale of 6L 6s, expanding it by 12 tones. Generators that produce this scale range from 150¢ to 200¢, or from 0¢ to 50¢.
