-@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 |
-}
-
-versewords = \lyricmode {
- One two three | four five six |
-}
-
-\score {
- \new ChoirStaff {
- \new Staff <<
- \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 <<
- \new Voice = "refrainB" @{
- \refrainnotesB
- @}
- \new Lyrics \lyricsto "refrainB" @{
- \refrainwordsB
- @}
- >>
->>
-@end example
-
-Here's the final result with two staves in the chorus showing
-how the parallel section is positioned within the verse Voice:

-@lilypond[quote,verbatim, ragged-right]
-versenotes = \relative c'' {
- \clef "treble"
- \key g \major
- \time 3/4

- la la | la la |

-refrainnotesB = \relative c {
- \clef "bass"

+@cindex stretchability of staves
+@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.

+
+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"
+ \new Voice @{
+ \voiceOne
+ \ManualOneVoiceOneMusic
+ @}
+ \new Voice @{
+ \voiceTwo

+ >> % end ManualOne Staff context
+ \new Staff = "ManualTwo" \with @{

will have a similar structure, although the number of voices
