=== 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 | |||
