10L 9s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 10 large steps and 9 small steps, repeating every octave. 10L 9s is a child scale of 9L 1s, expanding it by 9 tones. Generators that produce this scale range from 1073.7 ¢ to 1080 ¢, or from 120 ¢ to 126.3 ¢. The 10L 9s MOS scale divides its large steps 2-1-1-1-1-1-1-1-1 like the 10edo nonatonic scale. Its 'trienthird' generator falls in the narrow range of 1/10edo (120) to 2/19edo (126.316 cents).
