5L 20s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 5 large steps and 20 small steps, with a period of 1 large step and 4 small steps that repeats every 240.0 ¢, or 5 times every octave. 5L 20s is a great-grandchild scale of 5L 5s, expanding it by 15 tones. Generators that produce this scale range from 192 ¢ to 240 ¢, or from 0 ¢ to 48 ¢.
