Hmmm, that sounds difficult. I assume your leadSheet contains chords and
staves like e.g.
% -----------------------------------------------
leadSheet = {
<<
\new ChordNames {
% \italianChords % maybe yes, maybe no...
\chordmode {
c1 g
}
}
\new Staff {
\relative c' {
c4 d e f g1
}
}
>>
}
% -----------------------------------------------
AFAIK this definition is static and I know no override that could change
things at a later time.
[To anybody reading this: Please correct me if I'm wrong. ;-) ]
But you could turn your "leadSheet" variable into a music function that
takes a boolean parameter telling if to use italian chords or not:
% -------------------------------------------------------------
\version "2.19.83"
leadSheet = #(define-music-function (useItalianChords) (boolean?)
#{
<<
\new ChordNames {
#(if useItalianChords #{ \italianChords #})
c1 g
}
\new Staff \relative c' {
c4 d e f g1
}
>>
#}
)
\book {
\bookOutputSuffix "G"
\header { subtitle = "(G)" }
\score {
\transpose c b
\leadSheet ##f
}
}
\book {
\bookOutputSuffix "F"
\header { subtitle = "(F)" }
\score {
\transpose c a
\leadSheet ##f
}
}
\book {
\bookOutputSuffix "F-ita"
\header { subtitle = "(F)" }
\score {
\transpose c a
\leadSheet ##t
}
}
% -------------------------------------------------------------
Another possibility would be to define separate variables for your chords
and notes:
% -----------------------------------------------
\version "2.19.83"
leadSheetChords = \chordmode {
c1 g
}
leadSheetNotes = \relative c' {
c4 d e f g1
}
% In your \book parts, use this construction:
{
<<
\new ChordNames {
\italianChords % maybe yes, maybe no...
\leadSheetChords
}
\new Staff {
\leadSheetNotes
}
>>
}
% -----------------------------------------------
Cheers,
Klaus
