9L 1s is a MOS pattern generated by a two-third tone or small "trienthird" of 1/10edo (120 cents) to 1/9 (133.333). It appears as the "diatonic" scale in temperaments such as Negri and Twothirdtonic.
Names
The TAMNAMS system calls this scale pattern sinatonic after sinaic, a proposed interval category name for 14/13-like intervals that generate the scale. Graham Breed's MOS naming calls this the "Grumpy" decatonic scale.
