Function for standardized voice-blocks

[Michael Schweiger]

Dear Sirs:

I failed creating a function for putting together polyphonic music from
pre-formed blocks. Perhaps this following little example shows you what I tried
to do, so that you perhaps can help me.

{
bassPartA = {c4 d e f}
bassPartB = {g4 f e d}

tenorPartA = {c'4 b a g}
tenorPartB = {f4 g a b}

myOpus = #(define-music-function (parser location myvoice)
 (string?)
 #{ \#&myvoicePartA
    \#&myvoicePartB
    \#&myvoicePartA
 #})

\score {
          \new ChoirStaff <<
                \new Staff = tenor { 
                       \myOpus tenor
                  }
                \new Staff = bass {
                       \myOpus bass
                  } >>
        }
}



As you surely see, this should print e.g. a bass-melody thats {c4 d e f g4 f e d
c4 d e f}.
But there are some deeper mistakes I made in setting up the function and has'nt
been able to solve by finding something compareble in the manual. Perhaps you
can help me.

Many thanks in advance!

Yours sincerely
