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.

Step sizes in more complex oneirotonic edos. Finding the defining enharmonic equivalences is left up to the reader.

  • 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
