Re: Nesting ly:music-property error

[Michael Ellis]

Hi Scott,

I think the problem is that the music in your example doesn't have an
'elements property.  You can eliminate the error by changing the third
line in your code to

#(display-scheme-music (ly:music-property $myx 'pitch))

but what gets displayed is an empty list '().  Probably not what you
want, right?

Some of the more experienced Schemers on the list may be able to offer
better help.

Cheers,
Mike
