@code{\score} command, leaving the others to default.

-- one will be implicitly created. However, if you would like

music. If a Voice context is not explicitly declared one is created
automatically, as we saw at the beginning of this chapter. Some
instruments such as an Oboe can play only one note at a time. Music
-written for such instruments is monophonic and requires just a single
-voice. Instruments which can play more than one note at a time like
-the piano will often require multiple voices to encode the different
-concurrent notes and rhythms they are capable of playing.

A single voice can contain many notes in a chord, of course,
so when exactly are multiple voices needed? Look first at
this example of four chords:
-@lilypond[quote,verbatim,fragment,ragged-right,relative=1]
+@lilypond[quote,verbatim,ragged-right,relative=1]
\key g \major

+symbols, @code{< @dots{} >}, and for this just a single voice is
needed. But suppose the F-sharp were actually an eighth-note
followed by an eighth-note G, a passing note on the way to the A?
Now we have two notes which start at the same time but have
@funindex \\
The easiest way to enter fragments with more than one voice on a
-staff is to enter each voice as a sequence (with @code{@{...@}}),
-and combine them simultaneously with angle brackets, @code{<<...>>}.
+staff is to enter each voice as a sequence (with @code{@{ @dots{} @}}),
+and combine them simultaneously with angle brackets, @code{<< @dots{} >>}.
The fragments must also be separated with double backward slashes,
@code{\\}, to place them in separate voices. Without these, the
notes would be entered into a single voice, which would usually
cause errors. This technique is particularly suited to pieces of
-music which are largely monophonic with occasional short sections
+music which are largely homophonic with occasional short sections
of polyphony.
Here's how we split the chords above into two voices and add both
the passing note and a slur:
-@lilypond[quote,verbatim,fragment,ragged-right,relative=2]
+@lilypond[quote,verbatim,ragged-right,relative=2]
\key g \major
% Voice "1" Voice "2"
<< { g4 fis8( g) a4 g } \\ { d4 d d d } >>

+for each bar. For music with few notes in each bar this layout
can help the legibility of the code, but if there are many

This example has just two voices, but the same construct may be
used to encode three or more voices by adding more back-slash
separators.
The Voice contexts bear the names @code{"1"}, @code{"2"}, etc.
-In each of these contexts, the vertical direction of slurs,
-stems, ties, dynamics etc., is set appropriately.
+The first contexts set the @emph{outer} voices, the highest

-We see that this fixes the stem direction, but exposes a problem

-in one voice can collide with the note heads in other voices. In
-laying out the notes, LilyPond allows the notes or chords from two
-voices to occupy the same vertical note column provided the stems are
-in opposite directions, but the notes from the third and fourth voices
-are displaced, if necessary, to avoid the note heads colliding. This
-usually works well, but in this example the notes of the lowest voice
-are clearly not well placed by default. LilyPond provides several ways
-to adjust the horizontal placing of notes. We are not quite ready yet

-@cindex verse and refrain
-
-We end with an example to show how we might code a solo verse which
-continues into a two-part refrain in two staves. The positioning
-of the sequential and simultaneous sections to achieve this within
-a single score is quite tricky, so follow the explanation carefully!
-
-Let's start with a score block containing a @code{ChoirStaff}, as
-we would like the brace to appear at the start of the chorus.
-Normally you would need angle brackets after @code{\new ChoirStaff}
-to bring in all the staves in parallel, but here we want to
-defer the parallelism during the solo so we use braces, although
-angle brackets here wouldn't hurt. Inside the @code{ChoirStaff} we
-want first the staff which will contain the verse. This must
-contain notes and lyrics in parallel, so here we need angle
-brackets around the @code{\new Voice} and @code{\new Lyrics} to
-start them at the same time:
-
-@lilypond[quote,verbatim,ragged-right]
-versenotes = \relative c'' {
- \clef "treble"
- \key g \major
- \time 3/4
- g4 g g | b4 b b |

- \new Voice = "verse" {
- \versenotes \break
- }
- \new Lyrics \lyricsto verse {
- \versewords
- }
- >>
- }
-}
-@end lilypond
-
-That gives the verse line.
-
-Now we want to continue with refrainA on the same staff while a
-second staff is introduced in parallel with it for refrainB, so
-this is a parallel section which must be positioned immediately
-following the @code{\break} in the verse Voice. Yes, @emph{within}
-the verse Voice! Here's that parallel section. More staves
-could be introduced here in the same way.
-
-@example
-<<
- \refrainnotesA
- \new Lyrics \lyricsto verse @{
- \refrainwordsA

- \new Staff <<

+@cindex staves, stretchability
+
+The above layout of the organ staves is almost perfect; however,
+there is a slight defect which is not visible by looking at just a
+single system: The distance of the pedal staff to the left hand staff
+should behave approximately the same as the right hand staff to the
+left hand staff. In particular, the stretchability of staves in a
+@code{PianoStaff} context is limited (so that the distance between
+the staves for the left and right hand can't become too large), and
+the pedal staff should behave similarly.
+
+@cindex sub-properties

+
+Stretchability of staves can be controlled with the
+@code{staff-staff-spacing} property of the
+@code{VerticalAxisGroup} @q{graphical object} (commonly called
+@q{grob}s within the lilypond documentation) -- don't worry about
+the details right now; this is fully explained later. For the
+curious, have a look at @ruser{Overview of modifying properties}.
+In this case, we want to modify the @code{stretchability}
+sub-property only. Again, for the curious, you can find the
+default values for the staff-staff-spacing property
+in file @file{scm/define-grobs.scm} by looking up the definition
+of the @code{VerticalAxisGroup} grob. The value for
+@code{stretchability} is taken from the definition of the
+@code{PianoStaff} context (in file @file{ly/engraver-init.ly})
+so that the values are identical.
+
+@example
+\score @{
+ << % PianoStaff and Pedal Staff must be simultaneous
+ \new PianoStaff <<
+ \new Staff = "ManualOne" <<
+ \keyTime % set key and time signature
+ \clef "treble"
