Reticular ~~Intonation~~ (RI) is the theory and practice of using an interval audibly (very) distinct from 2/1 (or its multiples) directly as the base of a [[~~Just_intonation|~~just]] or tempered scale (said interval here assumed the interval of equivalence of this scale). In theory, the interval chosen may be any member of this infinite set. However, the practical utility of most intervals as bases of RI scales is limited by their being either so narrow as to seriously muddy the close voicings of triads (e. g. the [[EDF|fifth]]) or so wide as to create scales which do not entirely cohere (e.g. the [[edt|tritave]]).

'''Reticular intonation''' ('''RI'''){{idiosyncratic}} (term proposed by diagonalia) is the theory and practice of using an interval audibly (very) distinct from 2/1 (or its multiples) directly as the base of a [[just]] or [[tempered]] scale (said interval here assumed the [[interval of equivalence]] of this scale). In theory, the interval chosen may be any member of this infinite set.

Largely in theory, then, the types of RI are the following:
