Re: defining custom note heads

[V!ctor Adán]

Hello Eric, 

here are a few more examples. 
The first (headCircle) is the one I had given before. It just  calls musicgryph inside a markup.
The second (headTriW) just draws a triangle. Notice how you can set the size with the fontsize command.
The third (headXinD) combines (with the combine directive) a drawn circle (draw-circle) with a mysicglyph.

Notice how "halign" and "lower" are used to move things around.

Hope these help,

Victor.

I have it working when you define glyphs, like this:

headCircle  = {\once \override NoteHead  #'stencil = #ly:text-interface::print
             \once \override NoteHead #'text = #(markup #:musicglyph
"scripts.flageolet" ) }

What I can't get to work is what Victor mentioned but didn't give and
example for. Here's what he said,

 "But you can also draw lines, circles, etc. basically anything you can
do in a markup. See
http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Text-markup-commands#Text-markup-commands"

I can't figure out the exact syntax for when you use markup and not a
glyph. I would love an example like the one above with markup.

Thanks,

-Eric
