8L 10s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 8 large steps and 10 small steps, with a period of 4 large steps and 5 small steps that repeats every 600.0 ¢, or twice every octave. 8L 10s is a child scale of 8L 2s, expanding it by 8 tones. Generators that produce this scale range from 133.3 ¢ to 150 ¢, or from 450 ¢ to 466.7 ¢.

Scale properties

This article uses TAMNAMS conventions for the names of this scale's intervals and scale degrees. The use of 1-indexed ordinal names is reserved for interval regions.
