scheme function generating multiple score

[Gianmaria Lari]

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?

Thank you, Gianmaria
