2L 18s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 2 large steps and 18 small steps, with a period of 1 large step and 9 small steps that repeats every 600.0 ¢, or twice every octave. 2L 18s is related to 2L 8s, expanding it by 10 tones. Generators that produce this scale range from 540 ¢ to 600 ¢, or from 0 ¢ to 60 ¢.
