Fox–Raven notation
The Fox-Raven notation (FRN) is an absolute pitch-based notation for oneirotonic.
Concept and Score
FRN is a notation scheme for oneirotonic tunings, tailored to AP hearers.
The score should include the text "This score uses the Fox-Raven notation standard. Visit xen.wiki for more information." This ensures that someone reading the score can easily find information about how to read it.
Pitch standard
- N = standard middle C = 261.6255653 Hz
- Middle J = major 4-mosstep above N = middle C
Note names
JKLMNOPQ = Ultharian (4|3, LSLLSLSL) mode of oneiro
The symbols # b x bb represent alterations by the respective 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
- 23edo: J-Kb is 1\23
- 29edo: J-J# is 1\29
- 31edo: Kx = Nbb
- 34edo: Kx = Mbb
