This is the [[chromatic]] scale of Golden [[diminished]] temperament. It is always [[proper]] because it has one small step per period and is generated by its large step of 1\12edo to 1\8edo.

8L 4s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 8 large steps and 4 small steps, with a period of 2 large steps and 1 small step that repeats every 300.0 ¢, or 4 times every octave. 8L 4s is a child scale of 4L 4s, expanding it by 4 tones. Generators that produce this scale range from 100 ¢ to 150 ¢, or from 150 ¢ to 200 ¢. Scales of the true MOS form, where every period is the same, are proper because there is only one small step per period. This is the chromatic scale of Golden diminished temperament.
