* resolve the 600 tritone inwards to 467 or outwards to 733 instead of a traditional third
* resolve the 600 tritone inwards to 467 or outwards to 733 instead of a traditional third
=== Modulation ===
Some important modulatory intervals in 18edo:
5ths and 4ths
* sup5 / sub4, sub5 / sup4
3rds and 6ths
* maj3 / min6, supmin3 / submaj6, submin3 / supmaj6
2nds
* maj2 / min7 (maj2 = sup5 + sub5 = 3*sub4 = 3*submaj6) -- these are familiar
Dissonances
* supmin2 / submaj7, submin2 / supmaj7, tritone
Sup and sub cancel and result in a 12edo (actually 6edo) interval. So do 3 sup's and 3 sub's, as one sup/sub = ±1\36.
sub5/sup4 forms a 9edo subset, maj3 forms 3edo subset, maj2 forms 6edo subset. supmin3 and sub4 form complete cycles
