Oups, avec les bons instruments c'est mieux :

\version "2.18.2"

global = {
  \time 2/2
  \key a\major
}

musiqueUn = {
  \set Staff.shortInstrumentName = "It1"
  \global
  \repeat unfold 20 { s1 }
  \stopStaff
  \break
  %{
  \omit Staff.Clef
  \omit Staff.TimeSignature
  \omit Staff.KeySignature
  %}
  \override Staff.Clef.stencil = ##f
  \override Staff.KeySignature.stencil = ##f
  \override Staff.TimeSignature.stencil = ##f
  \unset Staff.shortInstrumentName
  s1
  %\omit Staff.BarLine
  \override Staff.BarLine.stencil = ##f
  \repeat unfold 89 { s1 }
  \startStaff 
  %{
  \undo\omit Staff.Clef
  \undo\omit Staff.TimeSignature
  \undo\omit Staff.KeySignature
  %}
  \revert Staff.Clef.stencil
  \revert Staff.KeySignature.stencil
  \revert Staff.TimeSignature.stencil
  \tag instUn { \set Staff.shortInstrumentName = "It1" }
  \tag instDeux { \set Staff.shortInstrumentName = "It2" }
  \break

  \repeat unfold 29 { s1 }
  \bar "|."
}

musiqueDeux = {
  \global
  \repeat unfold 140 { s1 }
  \bar "|."
}

\score {
