Is it possible to avoid the two lines

mybook = #(myBook #{ { c' d' e' } #})
\mybook

and write directly something like

 myBook #{ { c' d' e' } #}

?

oh, great! It was some weeks I was stuck with this issue. I thought the
scheme function would simply copy everything inside the #{ ... #} replacing
the variable.

Thanks a lot Timothy!

This code generate two scores:

\score {

\score {

I tried to write a scheme function doing something similar:

\version "2.19.80"
myScore = #(define-scheme-function (music) (ly:music?) #{

\score {

\myScore {c' d' e'}

but when I try to compile I get this error


error: syntax error, unexpected \score, expecting end of input

\score {


error: error in #{ ... #}


Any suggestion?
Thank you, Gianmaria



A function can only return a single item so you could wrap the two 
scores in a book and then process the book.


\version "2.19.80"

myBook = #(define-scheme-function (music) (ly:music?) #{
  \book {
    \score { \transpose c d $music \layout{} }
    \score { \transpose c e $music \layout{} }
  }
#})

mybook = #(myBook #{ { c' d' e' } #})
\mybook

scheme function generating multiple score

Sorry to bother but I'm unable to get out from this problem.
This code generate two scores:

\version "2.19.80"

\score {
  \transpose c d {c' d' e'}
  \layout{}
}

\score {
  \transpose c e {c' d' e'}
  \layout{}
}

I tried to write a scheme function doing something similar:

\version "2.19.80"
myScore = #(define-scheme-function (music) (ly:music?) #{

  \score {
\transpose c d $music
\layout{}
  }

  \score {
\transpose c e $music
\layout{}
  }

#})

\myScore {c' d' e'}

but when I try to compile I get this error


error: syntax error, unexpected \score, expecting end of input

\score {


error: error in #{ ... #}


Any suggestion?
