Evening all.
I've been working on some scheme functions currently working on displaying
theactual scheme coding while referring primarily to 6.3.2 Music Properties
The following is working
_______________________________________________________
myN = #(define-music-function (parser location myx ) (ly:music?)
#{
#(display-scheme-music (ly:music-property $myx 'elements))
#})
\myN c
Which Returned ==>
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch -1 0 0)))
________________________________________________________
However when I try and display the pitch only with
________________________________________________________
myN = #(define-music-function (parser location myx ) (ly:music?)
#{
#(display-scheme-music (ly:music-property (ly:music-property $myx
'elements)'pitch))
#})
\myN c
I get an error
GNU lilypond 2.12.3
Processing "displaymusic.ly"
Parsing...
<string>:2:1: error: GUILE signaled an error for the expression beginninghere
#<display-scheme-music (ly:music-property (ly:music-property lilyvartmpb(quote
elements)) (quote pitch)))
Wrong type argument in position 1 (expecting Music): (#(Prob: Music

parser))) (name .NoteEvent) (types general-music event note-event rythmis-event
melodic-event))>
)
displaymusic/ly:0: warning: no \version statement found, please add

for future compatibility

_________________________________________________________
I've looked at the manual several times and haven't recognized a solution.
So what am I missing?
Thanks Scott
