This page is about of a MOSScale with 7 large steps and 2 small steps arranged LLLsLLLLs (or any rotation of that, such as LLsLLLsLL).

Name

The name superdiatonic has been established by Armodue theorists, and so TAMNAMS adopts it as well.

Temperaments

If you're looking for highly accurate scales (that is, ones that approximate JI closely), there are much better scale patterns to look at. However, if your harmonic entropy is coarse enough (that is, if 678 cents is an acceptable '3/2' to you), then mavila is an important harmonic entropy minimum here. So a general name for this MOS pattern could be "Mavila Superdiatonic" or simply 'Superdiatonic'.

These scales are strongly associated with the Armodue project/system applied to septimal mavila and Hornbostel temperaments.

Intervals

Note: In TAMNAMS, a k-step interval class in superdiatonic may be called a "k-step", "k-mosstep", or "k-armstep". 1-indexed terms such as "mos(k+1)th" are discouraged for non-diatonic mosses.
