+Natural harmonics can be notated in several ways. A diamond-shaped
+note head generally means to touch the string where you would stop
+the note if it were not a diamond.
+
+@warning{Harmonics @strong{must} be defined inside a chord
+construct even if there is only a single note.}
+
+@c TODO If the default for harmonicDots is changed, change this
+Dotted harmonics indicated with @code{\harmonic} do not show the
+dots. The context property @code{harmonicDots} should be set if
+dots are required.

+
+Alternatively a normal note head is shown at the pitch to be
+sounded together with a small circle to indicate it should be
+played as a harmonic:
+
+@lilypond[verbatim,quote,relative=2]
+d2^\flageolet d_\flageolet
+@end lilypond
+
+A smaller circle may be created, see the snippet list in
+@ref{References for unfretted strings}.

+
+@cindex artificial harmonics
+@cindex harmonics, artifical
+
+Artificial harmonics are notated with two notes, one with a normal
+note head indicating the stopped position and one with an open
+diamond note head to indicate the harmonic position.
