+This orchestral score example consists of three input files. In the
+first file, @file{os-music.ly}, we define the music for all instruments.
+This file is to be used by the other two files, as you will see below.
+If you run lilypond on this file, no output will be produced.
+

@example
+% os-music.ly

+Things to note here are the definition of @code{\global} where we define
+meter, and set the end bar. And the separate definition of @code{\Key}
+that we will use all staffs except staffs for transposing instruments.
+
+The second file, @file{os-score.ly} reads the definitions of the first
+(@file{os-music.ly}), and defines the @code{\score} block for the full
+conductor's score.

+
+First, we need to include the music definitions we made in
+@file{os-music.ly}.
+@example
+\include "os-music.ly";
+@end example
+
+In a large orchestral score like this you're bound to make some small
+mistakes, so we enable point and click (See @ref{Point and click})
+editing.
+@example
+#(set! point-and-click #t)
+@end example
+
+We need a flat to specify the tuning of the french horn, so we predefine
+it with bit of scheme markup text (See @ref{Text markup}).
+@example
+#(define text-flat '((font-relative-size . -2)
+ (music "accidentals--1")))
+@end example
+
+Of course, all staffs are simultaneous and use the same global settings.
+@example
+ <
+ \global
+@end example
+
+Then, we start a new staff group for the woodwind section (just the
+flutes in this case). Immediately after that, we start the staff for
+the two flutes, that also play simultaneously.
+@example
+ \context StaffGroup = woodwind <
+ \context Staff = flauti <
+@end example
+
+We specify the intrument for MIDI output (see @ref{MIDI instrument
+names}).
+@example
+ \property Staff.midiInstrument = #"flute"
+@end example
+
+And define the intrument names to be printed in the margin,
+@code{instrument} for the first line of the score, @code{instr} for the
+rest of the score.
+@example
+ \property Staff.instrument = "2 Flauti"
+ \property Staff.instr = "Fl."
+@end example
+
+The flutes play in the default key.
+@example
+ \Key
+@end example
+
+Last come the actual flute parts. Remember that we're still in
+simultaneous mode. We name both voices differently, so that LilyPond
+will actually create two Voice contexts. The flute parts are simple, so
+we specify manually which voice is which: @code{\voiceOne} forces the
+direction of stems, beams, slurs and ties up, @code{\voiceTwo} sets
+directions down.
+@example
+ \context Voice=one @{ \voiceOne \flautoI @}
+ \context Voice=two @{ \voiceTwo \flautoII @}
+@end example
+
+We close the flutes staff and woodwind staff group.
+@example
+ >
+ >
+@end example
+
+The timpani staff only shows a new piece of scheme markup, it sets two
+lines of text.
+@example
+ \property Staff.instrument = #'(lines "Timpani" "(C-G)")
+@end example
+
+For the trumpets we use the automatic part combiner (see @ref{Automatic
+part combining}) to combine the two simultaneous trumpet parts onto the
+trumpet staff. Each trumpet gets its own Thread context, which must be
+named @code{one} and @code{two}). The part combiner makes these two
+threads share a Voice when they're similar, and splits the threads up
+when they're different.
+@example
+ \context Voice=one \partcombine Voice
+ \context Thread=one \tromboI
+ \context Thread=two \tromboII
+@end example
+
+The french horn has the most complex scheme markup name, made up of two
+lines of text. The second line has two elements (rows), the @code{E}
+and the flat sign @code{text-flat} that we defined before.
+@example
+ \property Staff.instrument = #`(lines "Corno"
+ (rows "(E" ,text-flat ")"))
+@end example
+
+The french horn is to be tuned in E-flat, so we tell the MIDI backend to
+transpose this staff by three steps.
+@example
+ \property Staff.transposing = #3
+@end example
+
+Therefore, it has a different key.
+@example
+ \notes \key bes \major;
+@end example
+
+We specify a big indent for the first line and a small linewith for this
+tuturial.
+@example
+ indent = 15 * \staffspace;
+ linewidth = 60 * \staffspace;
+@end example
+
+Because we have a Thread representing one instument, we move the
+need the @code{Rest_engraver} from Voice to Thread level.
+@example
+ \translator@{
+ \ThreadContext
+ \consists "Rest_engraver";
+ @}
+ \translator@{
+ \VoiceContext
+ \remove "Rest_engraver";
+ @}
+@end example
+
+In orchestral scores, it often happens that one instrument has only
+rests during one line of the score. The @code{HaraKiriStaffContext} can
+be used as a regular @code{StaffContext} drop-in and will take care of
+the automatic removing of empty staffs.
+@example
+ \translator@{
+ \HaraKiriStaffContext
+ @}
+@end example
+
+Lastly, we want bar numbering at score level and want to move the bar
+number a few staff-spaces up.
+@example
+ \translator @{
+ \OrchestralScoreContext
+ BarNumber \override #'padding = #3
+ @}
+@end example

+The third file, @file{os-flute-2.ly} also reads the definitions of the
+first (@file{os-music.ly}), and defines the @code{\score} block for the
+second flute part.

+
+
+Because we separated the music definitions from the @code{\score}
+instantiations, we can easily define a second score from the music of
+the second flute. This then is the part for the second flute player.
+Of course, we make separate parts for all individual instruments.
+
+In this individual part the second flute has a whole staff for itself,
+so we don't want to force stem or tie directions.
+@example
+ \flautoII
+@end example
+
+The @code{\header} definitions were also read from @file{os-music.ly},
+but we need to set the instrument for this particular score.
+@example
+ \header @{
+ instrument = "Flauto II";
+ @}
+@end example
+
+In the conductor's full score, all bars with rests are printed, but for
+the individual parts, we want to contract pieces of consecutive empty
+bars.
+@example
+ skipBars = ##t
