+@item additionalPitchPrefix
+
+When the chord name contains additional pitches, they can optionally
+be prefixed with some text. The default is no prefix, in order to
+avoid too much visual clutter, but for small numbers of additional
+pitches this can be visually effective.

The second item is a markup that will follow the @code{chordRootNamer}
output to create the chord name.
+@funindex minorChordModifier
+
+@item minorChordModifier
+
+Minor chords are often denoted via a @q{m} suffix to the right of the
+root of the chord. However some idioms prefer other suffices, such as
+a minus sign.

-The @q{m} for minor chords is usually printed immediately to the

-the root and @q{m} by setting @code{chordPrefixSpacer}.
-The spacer is not used when the root is altered.
