Letters standing for musical pitches (which in turn are used to identify keys, chords, and so on) are usually set as roman capitals. The terms sharp, flat, and natural, if spelled out, are set in roman type and preceded by a hyphen. Editors unfamiliar with musicological conventions should proceed with caution. In the context of harmony, for example, some authors may regard a hyphenated “C-major triad” as being based on the note rather than the key of C. See also 7.74.
A series of pitches are joined by en dashes.
