Original Wikitext content:
There may be a better name for this. This is an attempt to name a very common pattern in [[Notation|notating]] microtonal pitch systems. These are analogic extensions of basic Western music notation of [[12edo]]. **Nominal** means that you give some pitches in your scale specific names. In Western music notation, the seven naturals A B C D E F G are given these names. (Historically, H has also been used.) **Accidental** means that for the pitches without names, you name them as modifications (accidentals) of the named pitches. In Western music notation, the five "black keys" are named by adding "sharp" or "flat" to A-G. **[[Enharmonic equivalence]]** may arise from this approach. This is when you have multiple names for the same pitch. C-sharp is enharmonically equivalent to D-flat, but only in 12-EDO! This page is incomplete, and will eventually contain or refer to * How to use A-G circle-of-fifths notation to notate any tuning with a circle of fifths * Non-A-G extensions, including Erv Wilson's greek letters, Bohlen-Pierce notation, Armodue number notation * Mark Gould's connection of accidentals to bi-level MOS * the term "albitonic" * Connections to Sagittal notation proposal & Aaron Hunt's system
