A more structural, lattice-based approach is [[detempering]]. Detempering entails that the neji has the property of being [[epimorphic]] (obeys a mapping logic under some val) with respect to a temperament for a tempered scale, equal-division or otherwise. | A more structural, lattice-based approach is [[detempering]].

One might choose a low harmonic series mode and selecg notes therefrom in order to build an edo neji with extra concordance. Such a neji can be described as a "harmodal neji", from "harmonic mode". | One might choose a low harmonic series mode and selecg notes therefrom in order to build an edo neji with extra concordance.

This distinction is more process-based than formalized, in that the pool of intervals is chosen to be some mode m::2m, before notes are selected from it. This is hecause any JI scale occurs as some (possibly very high) harmonic series segment. | This distinction is more process-based than formalized, in that the pool of intervals is chosen to be some mode m::2m, before notes are selected from it.

It's possible to create a working harmodal edo neji by simply approximating an edo as closely as possible with selected harmonics from a mode. However, it is sometimes preferable to build particular aesthetic choices into such a neji. One such common choice is to focus on a few intervals in the edo being "nejified" which are of particular interest. The root harmonic is then selected to approximate these intervals of interest as well as possible; the remaining harmonics to fill in the rest of the edo are chosen based on their ability to fit well with the existing notes. | It's possible to create a working harmodal edo neji by simply approximating an edo as closely as possible with selected harmonics from a mode.
