spelling

The way in which a note of a given pitch is specified by a letter name plus an accidental. For example, assuming the conventional 12-EDO pitch system, MIDI note 61 can be spelled as C♯, D♭, and B. The same pitch is normally spelled a certain way in a given key; for example, MIDI note 61 is normally spelled as C♯ in D major, but is spelled as D♭ in A♭ major. See also EDO, MIDI.
