9L 9s
9L 9s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 9 large steps and 9 small steps, with a period of 1 large step and 1 small step that repeats every 133.3 ¢, or 9 times every octave. Generators that produce this scale range from 66.7 ¢ to 133.3 ¢, or from 0 ¢ to 66.7 ¢. Scales of the true MOS form, where every period is the same, are proper because there is only one small step per period.
