The scale that has minimum ambiguity between notes is always an [[equal]] scale.
The scale that has minimum ambiguity between notes is always an [[equal]] scale.


The DE scale of ''N'' notes that has strictly minimum ambiguity between intervals is always a subscale of ({{nowrap| 2''N'' - ''P'' }})-edo, where ''P'' is the number of periods per octave. (Octave-repeating scales are assumed here, but in fact the minimum ambiguity property is insensitive to any stretching or compressing, so the same scale patterns apply as equal divisions of any interval whatsoever.)

Scales are also listed that have some totally ambiguous (coinciding) intervals, but have minimum ambiguity over all other intervals.
