The default pitch standard in FRN is N4 ("middle N") = standard middle C = 261.63 Hz. The term "middle J" can be used for the note J4, which lies a major 4-[[TAMNAMS#Alternate_non-ordinal_names|mosstep]] above N4 = middle C. | The default pitch standard in FRN is {{nowrap|N4 ("middle N") {{=}} standard middle C}} {{nowrap|{{=}} 261.63 Hz}}.

The note names N4 O4 P4 Q4 J4 K4 L4 M4 N5 denote the Hlanithian (1|6 in UDP, sLLsLsLL) mode on N4 = C4. (This makes JKLMNOPQJ J Celephaisian or LsLLsLLs.) All octave transpositions of these notes have the number shifted by the appropriate amount. All alterations of a given note by accidentals have the same octave number as the original note. For example, in 13edo | The note names N4 O4 P4 Q4 J4 K4 L4 M4 N5 denote the Hlanithian (1|6 in UDP, sLLsLsLL) mode on {{nowrap|N4 {{=}} C4}}. (This makes JKLMNOPQJ J Celephaisian or LsLLsLLs.) All octave transpositions of these notes have the number shifted by the appropriate amount. All alterations of a given note by accidentals have the same octave number as the original note. For example, in 13edo N♭4 is the note 1\13 below N4, and is enharmonic with M♯3. | ||

* | * Sharps and flats {{nowrap|(♯ / ♭)}} represent alteration by one moschroma (L − s). | ||
* | * Double sharps and double flats {{nowrap|(𝄪 / 𝄫)}} represent alteration by two moschomas. | ||
* | * Semisharps and semiflats {{nowrap|({{demisharp2}} / {{demiflat2}})}} represent half-moschromas in systems such as 18edo and 26edo where the moschroma can be split into two equal parts. These cannot be used in systems that do not split the oneirotonic chroma into two equal parts, such as 21edo. | ||
* In edo systems, ^ v denote alteration by one edo step. They can still be used when a detuned edo (such as a neji) is notated as the edo, but cannot be used when the notation is not edo-based (e.g. based on a consistent non-edo oneirotonic generator). | * Sesquisharps and sesquiflats {{nowrap|({{sesquisharp2}} / {{sesquiflat2}})}} alter by one-and-one-half moschromas. | ||
* In edo systems, ups and downs (^ v) denote alteration by one edo step. They can still be used when a detuned edo (such as a neji) is notated as the edo, but cannot be used when the notation is not edo-based (e.g. based on a consistent non-edo oneirotonic generator). | |||

A subtle but important feature of the standard is that accidentals are separate from each other and do not stack.

For example, if a K with a ♯ is followed by a K with only an ^, the second note is K^, not K^♯. | ||
