Can anybody give me some suggestions of how I would draw an oval around a
group of notes on the staff?
For the special case of a single chord, see the german thread
http://www.lilypondforum.de/index.php?topic=378
The 2.18 version of this would read
%%%%%%%%%%
kringel =
\once \override NoteColumn.stencil = #(lambda (grob)
(let* ((xext (ly:grob-extent grob grob X))
(yext (ly:grob-extent grob grob Y))
(xpos (interval-index xext CENTER))
(ypos (interval-index yext CENTER))
(yrad (* 0.8 (interval-length yext)))
(xrad (min (interval-length xext) 2))
(thickness 0.05))
(ly:stencil-add
(ly:stencil-translate
(ly:make-stencil (list 'ellipse xrad yrad thickness #f))
(cons xpos ypos)) )))
%%%%%%%%%%
Cheers,
Robin
