Well, improvements are welcome :-)

You can't directly access the font name, it seems. Look at the
definition of the `musicglyph' markup command in
define-markup-commands.scm which uses ly:paper-get-font to get a font
handle for ly:font-get-glyph.
I assume the same is true for ly:get-glyph -- there is no example code
in lilypond which uses this function (which is, admittedly, not very
useful in general).
