Re: Note heads and grace

[Mats Bengtsson]

Don't ask me why, but if you replace Staff.NoteHead with Voice.NoteHead
in your example, it will work.

Also, I recommend to use \override ... \revert instead of explicitly
setting the value back to default:

\property Voice.NoteHead \override #'style = #'xcircle
c4 c c c
\property Voice.NoteHead \revert #'style
d4 d d d
\grace{d16 d}
d4 d d d
\property Voice.NoteHead \override #'style = #'xcircle
e4 e e e

See 
http://lilypond.org/doc/v2.0/Documentation/user/out-www/lilypond/Tuning-objects.html
for more details.

To do a setting for a single note head, use \once \property ...
You can define your own shorthand macro like
xcircle = \notes{ \once \property Voice.NoteHead \override #'style = 
#'xcircle }
and use it with
\xcircle c4
