IIRC, there is no way to obtain the current measure position
from the NoteHead grob itself ...
You can find the location by finding the PaperColumn grob which is
associated with the NoteHead. The properties 'rhythmic-location or
'when contain timing imformation. Here's a sketch:
\version "2.19.15"
#(define (get-paper-column grob)
(if (not (ly:grob? grob))
(ly:message "column not found")
(if (grob::has-interface grob 'paper-column-interface)
grob
(get-paper-column (ly:grob-parent grob X)))))
In current master, there is now a function ly:item-get-column which
returns the associated column.. (This will need to wait for the release
of 2.19.16.)
Yep, I replaced get-paper-column with ly:item-get-column in my code and
it works like a charm!
#(define (return-location grob)
(let ((col (get-paper-column grob)))
(display (ly:grob-property col 'rhythmic-location))
(newline)))
There are currently two functions being reviewed which will return
location data. The above would be covered by grob::rhythmic-location
(and there would be no need of looking for a paper column separately).

That's great news, I highly appreciate these new functions!
Thanks a lot,
Marc
