While 27edo is quite close to the zeta peak [[zpi|106zpi]], 22ed7/4 is quite close to the zeta peak [[zpi|107zpi]]. | |||
22ed7/4's mapping of prime 2 is very inconsistent. This might not necessarily be a bad thing, as it might allow for the perceived [[octave equivalence]] to fall on different scale degrees each octave or two. This could make each perceived octave sound different to the last, which may make the music more interesting to listen to in the hands of a skilled composer. | |||
Possible [[JI subgroup]]s for interpreting 22ed7/4 could be: | |||
* 2.3.5.7/2.11.13 | |||
or | |||
* 2.3.5.14.11.13 | |||
Though other interpretations could be possible as well. | |||
