Created page with "== Preamble == The Functional Just system is one of a kind. On the three systems of strict JI notation that I know: It, Johnson's system, and Helmholtz-Ellis; FJS is in my opinion, the most rigorous. It has been generalized to such an extent that it can provide a unique nomenclature to '''every single''' rational interval. Besides of course 0 and infinity. Its rigor, comes however with some unintuitive consequences, specially regarding the unintended consequences of a..."

Particularly in the case that one composer might want to write using FJS, and is accustomed to writing the augmented sixth from Ab as F#, and coming from experience in meantone temperaments (including the well-established 12EDO), ''feels'' that the interval 7/4 from Ab should be spelt Ab-F# because it will resolve to G, not Ab-Gb as the correct FJS might proscribe, leading to the possibly good sounding, but unintuitively written movement Ab4<sub>5</sub>,C5,Eb5<sub>5</sub>,Gb5<sup>7</sup><sub>5</sub> - G4,C5,E5<sup>5</sup>,G5. It is not a matter of correctness, but rather a matter of understanding and intuiting, both what the composer wants to write, and what the reader understands.

In my own experience, I feel that the interval 7/4 is ambivalent enough to serve as both a consonance like the major third, a type of minor seventh that might resolve down following a V<sup>7</sup> - I perfect cadence, or a type of augmented sixth that resolves up. Being able to both describe 7/4 as a minor seventh and an augmented sixth is a very useful ability for a JI notation system, even if it is not entirely rigorous.
