+There is little specialist notation for unfretted string
+instruments. The music is notated on a single staff, and
+usually only a single voice is required. Two voices might
+be required for some double-stopped or divisi passages.

+Most of the notation which is useful for orchestral strings
+and other bowed instruments is covered elsewhere:
+
+@itemize
+
+@item Textual indications such as @qq{pizz.} and @qq{arco} are
+added as simple text -- see @ref{Text scripts}.
+
+@item Fingerings, including the thumb indication, are described
+in @ref{Fingering instructions}.
+
+@item Double stopping is normally indicated by writing a chord,
+see @ref{Chorded notes}. Directives for playing chords may be
+added, see @ref{Arpeggio}.
+
+@item A template for a string quartet can be found in
+@rlearning{String quartet}. Others are shown in the snippets.

+Bowing indications are created as articulations, which are
+described in @ref{Articulations and ornamentations}.
+
+The bowing commands, @code{\upbow} and @code{\downbow}, are used
+with slurs as follows:
+
+@lilypond[verbatim,quote,relative=2]
+c4(\downbow d) e(\upbow f)
+@end lilypond
+
+@noindent
+and the following example shows three ways in which an open A
+string on a violin might be indicated:
+
+@lilypond[verbatim,quote,relative=2]
+a4 \open
+a^\markup { \teeny "II" }
+a2^\markup { \small "sul A" }

+
+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.
+
+@lilypond[verbatim,quote,relative=2]
+<d\harmonic>4 <e\harmonic>2.
+\set harmonicDots = ##t
+<d\harmonic>4 <e\harmonic>2.
+@end lilypond
+
+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
