==Generalization to non-octave scales==
==Generalization to non-octave scales==


It is possible to generalize the concept of consistency to non-edo equal temperaments. Because octaves are no longer equivalent, instead of an odd limit we must use an integer limit, and the term 2^n in the above equation is no longer present. Instead, the set S consists of all intervals u/v where u <= q >= v.

This also means that the concept of octave inversion no longer applies: in this example, [[13/9]] is in S, but [[18/13]] is not.

Alternatively, we can use "modulo-3 limit" if the [[equave]] is 3/1. Thus the tritave analogue of odd limit would allow integers not divisible by 3 under a given limit.
