Thanks! I can use this.

I would be very interested in the latter.

Sometimes, it could be as easy as:

  \aNotes = { ... }

  %%From template:
  \score {
     #(if (not (defined? bNotes))
          (define bNotes aNotes))
     \bNotes
  }

except that I cannot get this to work...

I'm afraid my lisp skills get in the way of lilyscheme :)
