From http://openmusictheory.com/triads.html
A lead-sheet symbol begins with a capital letter (and, if necessary,
an accidental) denoting the root of the chord.
That letter is followed by information about a chord’s quality:
- major triad: no quality symbol is added
- minor triad: lower-case “m”
- diminished triad: lower-case “dim” or a degree sign “°”
- augmented triad: lower-case “aug” or a plus sign “+”
