9L 11s
9L 2s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 9 large steps and 2 small steps, repeating every octave. 9L 2s is a child scale of 2L 7s, expanding it by 2 tones. Generators that produce this scale range from 654.5¢ to 666.7¢, or from 533.3¢ to 545.5¢.
It represents temperaments like Avila (narrow generator) and Casablanca (wide). There is no TAMNAMS name for this MOS, but CompactStar suggested the names ultradiatonic and superarmotonic by analogy to 7L 2s's name of superdiatonic.
