Fox–Raven notation

The Fox-Raven oneirotonic notation is an absolute pitch-based notation for oneirotonic.

Pitch standard

• N = standard middle C = 261.6255653 Hz
• Middle J = minor 4-mosstep above N = middle C

Note names

JKLMNOPQ = Ultharian (LSLLSLSL) mode

The symbols # b x bb represent alterations by the oneiro moschroma. t and d represent half-moschromas in systems such as 18edo and 26edo where the moschroma can be split into two equal parts.

The enharmonic equivalences that define each respective oneirotonic edo are:

• 13edo: K# = L
• 18edo: K# = Mb
• 21edo: K# = Lb
• 31edo: Kx = Mbb
• 34edo: Kx = Nbb
