Neji

A neji (pronounced /nɛdʒi/ "nedgy"; for "near-equal JI") or a quasi-equal rational tuning is a rational approximation of an EDO.

Nejis can be used to explore a prime family (see primodality), while keeping the transposability, scale structures, rank-2 harmonic theory, notation, etc. associated with that edo. (The neji's denominator need not be prime.)

Zhea Erose's theory also deals with modulations between different prime families, and combining different prime families into one scale.

History

The neji is probably first proposed by George Secor in 2002.
