A '''neji''' or '''NEJI''' (pronounced /nɛdʒi/ "nedgy"; for "near-equivalent [[just intonation]]") is a [[JI]] scale that is "nearly-equivalent" to an associated ''target scale'' (or ''target'' for short). Nejis are designed with a focus on the harmonic resonance of the pitches in mind w.r.t their foreseen musical use. If the target scale is an [[edo]], a neji is technically also a type of [[well temperament]] for that edo. | A '''neji''' or '''NEJI''' (which can be pronounced /nɛdʒi/ "nedgy"; for "near-equivalent [[just intonation]]" or "near-equal just intonation") is a [[JI]] scale that is "nearly-equivalent" to an associated ''target scale'' (or ''target'' for short).

It's possible to create a working 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 edo neji by simply approximating an edo as closely as possible with selected harmonics from a mode.

== Near-equal vs near-equivalent == | |||
The term "near-equal just intonation" may refer specifically to nejis where the target scale is an [[equal-step tuning]] (i.e. the notes of the neji are near-equally spaced), or it may refer to any and all nejis (i.e. the neji's step sizes are nearly equal to the target scale's step sizes). Both uses of the term are acceptable. | |||
The term "near-equivalent just intonation" refers to any and all nejis. It is interchangeable with the second reading of "near-equal". | |||
