No. (lambda ...) evaluates to a function, where you want a markup. Remember that the \number markup command takes a markup as an argument, not a procedure. When you want to parametrize (uh) a LilyPond expression, the first thing to do is to write it, in plain LilyPond syntax, and then display it in Scheme. Then you will have a pattern to use in your function body. (What you want is a music function, not a markup command). for instance, supposing that `mus:display' (see http://lists.gnu.org/archive/html/lilypond-devel/2004-11/msg00029.html) is defined in music-display.scm: -----test.ly----- #(load "music-display.scm") #(mus:display #{ R1^\markup \number 1 #}) -----test.ly----- lilypond test.ly ==> (make-music 'SequentialMusic 'elements (list (make-music 'MultiMeasureRestMusicGroup 'elements (list (make-music 'BarCheck) (make-music 'EventChord 'elements (list (make-music 'MultiMeasureRestEvent 'duration (ly:make-duration 0 0 1 1)))) (make-music 'BarCheck) (make-music 'TextScriptEvent 'direction 1 'text (list number-markup (markup #:simple "1"))))))) >>See scm/new-markups.scm. >> >> > I'll keep reading this but I don't understand it yet.

I don't know much about scheme community sites. www.schemers.org should have links to tutorials and books. nicolas _______________________________________________ lilypond-user mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/lilypond-user
