Re: How to insert a number for fingering in embedded LilyPond?

[Jan-Peter Voigt]

Hi Harm,

I assume, you want to use this in some music-function ... (?)
you can insert the displayed scheme-expression:

%%%
finger = #(define-event-function (parser location n)(integer?)
   (make-music 'FingeringEvent 'direction -1 'digit n))

{ c''4\finger 2 }

#(let ((n 4)) (display-scheme-music #{ \finger $n #}))
%%%

But unfortunately I don't know a shorter way to include it in such an
included lilyexpression ...
this would of course be handy, if you want to use parameters in a longer
snippet ...
