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.

- 23edo: J-J# is 3\23, J-K is 4\23, K-L is 1\23
- 29edo: J-J# is 1\29, J-K is 4\29, K-L is 3\23
- 31edo: J-J# is 3\31, J-K is 5\31, K-L is 2\31
- 34edo: J-J# is 2\34, J-K is 5\34, K-L is 3\34
