Moving a staff closer to another one

[Arle Lommel]

Hi all,

I have a piece with the following overall structure:

\score {

\new StaffGroup

<<

\new PianoStaff

<<

\new Staff = "RH" { \relative c' { \righthand } }

\new Staff = "LH" { \relative c { \lefthand } }

>>

\new Staff = "pedalMarks" \with {

\remove "Key_engraver"

\remove "Clef_engraver"

\remove "Staff_symbol_engraver"

\remove "Time_signature_engraver"

}

{

\relative c { \pedal }

}

>>

}

I would like to move the staff "pedalMarks" so that it sits substantially closer to the piano staff than the default spacing.

I have spent an few hours with the documentation at:

http://lilypond.org/doc/v2.16/Documentation/notation/flexible-vertical-spacing-within-systems

and I have had absolutely zero luck in getting anything there to work as I hoped it would.

I see the example with negative spacing (which is what I actually want, but I cannot seem to apply it to my case here).

Can anyone help me figure out how to get negative spacing here?

Best,

Arle
