'''Modeless interchange'''{{idiosyncratic}} is a technique used for chord progression, that consists of modulating over different types of 7-note [[MOS scale]]. In particular, an [[EDO]] in which all six types of 7-note MOSes can be realized is called '''interchangable''', and an EDO in which all 0-2-4 triads on all those 7-note MOSes are [[delta-rational]] is called '''perfectly interchangable'''.

'''Modeless interchange''' is a technique~~, commonly~~ used ~~in the form of a~~ chord progression, that consists of ~~crossing~~ over ~~the [[triad]] present in a~~ 7-note [[MOS scale]]. In particular, an [[EDO]] in which all six types of 7-note MOSes can be realized is called '''interchangable''', and an EDO in which all 0-2-4 triads on all those 7-note MOSes are [[delta-rational]] is called '''perfectly interchangable'''.

== Theory ==

There are six different 7-tone MOS scales, [[1L 6s]], [[2L 5s]], [[3L 4s]], [[4L 3s]], [[5L 2s]] and [[6L 1s]]. Each MOS is realized by a different set of EDOs, and not all EDOs can realize all of these MOSes. However, as mentioned above, there are EDOs in which all of these scales are simultaneously valid. Taking [[19edo]] as an example:

== Usage ==

This technique is still in its infancy and information is drying up, but it should be used like a modal interchange.

== Generalizations ==

Modeless interchange can be applied to MOSes with any number of notes, not just heptatonic ones.
