5L 18s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 5 large steps and 18 small steps, repeating every octave. 5L 18s is a great-grandchild scale of 5L 3s, expanding it by 15 tones. Generators that produce this scale range from 469.6 ¢ to 480 ¢, or from 720 ¢ to 730.4 ¢.
