Hi Dossy,

what David wrote may be illustrated by this example

\version "2.17.27"

\header {
    title = "TITLE"
    subtitle = "SUBTITLE"
    piece = "PIECE"
    composer = "COMPOSER"
}

introMusic =
    \new PianoStaff <<
    \new Staff \relative c' { \repeat unfold 8 c1 \bar "||" }
    \new Staff \relative c { \clef F \repeat unfold 8 c,1 }
    >>

restMusic =
    <<
    \new Staff {
      \new Voice = "mel" \relative c' { \repeat unfold 8 e'1 \bar "|." }
    }
    \new Lyrics \lyricsto "mel" \lyricmode { \repeat unfold 8 bla }
    \new FretBoards \chordmode { \repeat unfold 8 c:m }
    \new ChordNames \chordmode { \repeat unfold 8 c:m }

    \new PianoStaff <<
    \new Staff \relative c' { \repeat unfold 8 c1 }
    \new Staff \relative c { \clef F \repeat unfold 8 c,1 }
    >>
    >>

\score {
  {
    \introMusic
    \restMusic
  }
  \layout { }
  \midi { }
}


Though there is an spacing-issue with removing empty staves and the header.
Looking at the output of the following example the gap between header
and first system is too large.
It's a nuisance perhaps a bug, though one could work around it.
Comment in the \paper -section.

\version "2.17.27"

\header {
    title = "TITLE"
    subtitle = "SUBTITLE"
    piece = "PIECE"
    composer = "COMPOSER"
}

%\paper {
%    markup-system-spacing =
%          #'((basic-distance . 0)
%             (minimum-distance . 0)
%             (padding . -10)
%             (stretchability . 12))
%}

piano =
\new PianoStaff <<
\new Staff \relative c' {
    \mark "Intro"
    \repeat unfold 8 c'1 \bar "||" \break
    \mark "rest"
    \repeat unfold 8 c1 \break
    \repeat unfold 8 c1
}
\new Staff \relative c, {
    \clef F
    \repeat unfold 8 c1
    \repeat unfold 8 c1
    \repeat unfold 8 c1
}

voice =
\new Staff \new Voice = "lyr"\relative c' {
    \repeat unfold 8 s1
    \repeat unfold 16 e'
}

lyr =
\new Lyrics \lyricsto "lyr"
\lyricmode {
    \repeat unfold 16 bla
}

chrds =
\new ChordNames
\chordmode {
    \repeat unfold 8 s1
    \repeat unfold 16 c:m
}

fretboards =
\new FretBoards
\chordmode {
    \repeat unfold 8 s1
    \repeat unfold 16 c:m
}

\score {
