* [[Mavila]] is a commonly enough used word but inaccurate enough that it should be described not as a temperament but as a scale structure, i.e. [[7L 2s]] and its subsets or MODMOSes or extended harmony. It seems Erv Wilson defined mavila as a scale structure.

* Similarly [[Blackwood]] should be treated not as a temperament but as a synonym of [[5L 5s]] and its associated harmonic framework. (The [[20edo]] 5L 5s scale is often called blackwood, though it has 420¢ thirds thus is not a good tuning for blackwood temperament).

* [[Semaphore]] is redefined as the [[Step ratio|hard]]er-of-14edo [[5L 4s|semiquartal]] tuning range (period = 2/1, generator between 1\5 and 3\14), i.e. a [[5L 9s]]-based framework.

* [[Bug]] is redefined as the [[Step ratio|soft]]er-of-14edo [[5L 4s|semiquartal]] (period = 2/1, generator between 3\14 and 2\9), i.e. a [[9L 5s]]-based framework.
