Gregor,
How about this:
%%%%%%%%%%%%%%%%%
\version "2.19.36"
#(define (qBarNote grob)
(grob-interpret-markup grob
#{
\markup {
\concat {
\hspace #-0.06
\path #0.12
#'((moveto 0 -0.6)
(lineto 0 0.6))
\musicglyph #"noteheads.s2"
\hspace #-0.02
\path #0.12
#'((moveto 0 -0.6)
(lineto 0 0.6))
}
}
#}))
qBarNotesOn = {
\omit Stem
\override NoteHead.stencil = #qBarNote
}
qBarNotesOff = {
\undo \omit Stem
\revert NoteHead.stencil
}
\relative c' {
<c e f a>2 \qBarNotesOn q4 \qBarNotesOff q |
}
%%%%%%%%%%%%%%%%%
There's certainly more that could be done to make the functionality more
robust (like checking for duration, style, etc.), but this should at least
get you going.
HTH,
Abraham
