5L 15s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 5 large steps and 15 small steps, with a period of 1 large step and 3 small steps that repeats every 240.0¢, or 5 times every octave. 5L 15s is a grandchild scale of 5L 5s, expanding it by 10 tones. Generators that produce this scale range from 180¢ to 240¢, or from 0¢ to 60¢.
