===Switching between archeo- and oneirotonic modes===
==Switching between archeo- and oneirotonic==
An oneirotonic mode and an archeotonic mode based on the same tonic can share up to 6 notes; treat the unique diminished fourth in the oneirotonic scale as a major third spanned by two major seconds. Hence, pseudo-diatonic music in 13edo can easily use both archeotonic and oneirotonic as the situation requires, switching back and forth between a 7-note mode and a corresponding 8-note one.
