Hi Aaron, thanks for your reply. I tried your solution but again, it moves
either all the staves, or above and below a grand staff. This isn't the
ideal behaviour.

In the meantime, I found another solution for this, but this doesn't appear
to be the easiest way to do it! I used systemStartDelimiterHierarchy instead
which doesn't add any space within a family group. Again, with the LilyPond
exemple, this will give:

%---
fluteMusic = \relative c' { \key g \major g'1 b }
% Pitches as written on a manuscript for Clarinet in A
% are transposed to concert pitch.
clarinetMusic = \transpose c' a
  \relative c'' { \key bes \major bes1 d }
trumpetMusic = \relative c { \key g \major g''1 b }

% Key signature is often omitted for horns
hornMusic = \transpose c' f
  \relative c { d'1 fis }
percussionMusic = \relative c { \key g \major g1 b }
pianoRHMusic = \relative c { \key g \major g''1 b }
pianoLHMusic = \relative c { \clef bass \key g \major g1 b }
violinIMusic = \relative c' { \key g \major g'1 b }
violinIIMusic = \relative c' { \key g \major g'1 b }
violaMusic = \relative c { \clef alto \key g \major g'1 b }
celloMusic = \relative c { \clef bass \key g \major g1 b }
bassMusic = \relative c { \clef "bass_8" \key g \major g,1 b }

\score {
  <<
    \new StaffGroup = "StaffGroup_woodwinds" <<
      \new Staff = "Staff_flute" \with { instrumentName = #"Flute" }
      \fluteMusic
      \new Staff = "Staff_clarinet" \with {
        instrumentName = \markup { \concat { "Clarinet in B" \flat } }
      }
      % Declare that written Middle C in the music
      % to follow sounds a concert B flat, for
      % output using sounded pitches such as MIDI.
      %\transposition bes

      % Print music for a B-flat clarinet
      \transpose bes c' \clarinetMusic
    >>
    \new StaffGroup = "StaffGroup_brass" <<
      \new Staff = "Staff_hornI" \with { instrumentName = #"Horn in F" }
       % \transposition f
        \transpose f c' \hornMusic
      \new Staff = "Staff_trumpet" \with { instrumentName = #"Trumpet in  C"
}
      \trumpetMusic
    >>
    \new RhythmicStaff = "RhythmicStaff_percussion"
    \with { instrumentName = #"Percussion" }
    <<
      \percussionMusic
    >>
    \new PianoStaff \with { instrumentName = #"Piano" }
    <<
      \new Staff { \pianoRHMusic }
      \new Staff { \pianoLHMusic }
    >>    

    \new StaffGroup <<
      \set StaffGroup.systemStartDelimiterHierarchy = 
        #'(SystemStartBracket (SystemStartBrace (SystemStartBracket a) b) c)  
        \new Staff = "Staff_violinI" \with { instrumentName = #"Violin I" }
        \violinIMusic
        \new Staff = "Staff_violinII" \with { instrumentName = #"Violin II"
}
        \violinIIMusic
      \new Staff = "Staff_viola" \with { instrumentName = #"Viola" }
      \violaMusic
      \new Staff = "Staff_cello" \with { instrumentName = #"Cello" }
      \celloMusic
      \new Staff = "Staff_bass" \with { instrumentName = #"Double Bass" }
      \bassMusic
    >>
  >>
  \layout { }
}

%---

I would be interested if someone find another way to do this... But at
least, this seems to work!
