Hi Rachael,
the TabNoteHead already supports the text-interface.
\override TabNoteHead #'stencil = #ly:text-interface::print is needless than.
\override TabNoteHead #'text = \markup {...}
doesn't work, because a new text needs to be inserted very early in
the compiling-process, afaik.
You could use:
\version "2.16.2"
tick = {
\once \override TabNoteHead #'before-line-breaking =
#(lambda (grob)
(ly:grob-set-property!
grob
'text
#{ \markup { \musicglyph #"noteheads.s0la" } #} ))
}
\new TabStaff {
c8 \tick c8 c8 c8 }
Though, I'd prefer one of the following codings
(I recommend the second if you want to do more frequently)
\version "2.16.2"
%%%
% First possibility.
%%%
tick¹ = {
\once \override TabNoteHead #'stencil =
#(lambda (grob)
(grob-interpret-markup grob
#{
\markup { \musicglyph #"noteheads.s0la" }
#}))
}
%%%
% Second possibility.
%%%
#(define (new-stil markup)
;; Creates a stencil
(lambda (grob)
(grob-interpret-markup grob markup)))
newTabNoteHead =
#(define-music-function (parser location mrkp)(markup?)
;; Uses @code{new-stil} in a music-function.
;; Ofcourse it's possible to use:
;; @samp{\\once \\override TabNoteHead #'stencil =
;; #(new-stil #{ \\markup { \musicglyph #"noteheads.s0la" } #})}
;; directly.
#{
\once \override TabNoteHead #'stencil = #(new-stil mrkp)
#})
% creating a variable as sort of schortcut.
tick² = \newTabNoteHead \markup { \musicglyph #"noteheads.s0la" }
\new TabStaff {
\tabFullNotation
c8 \tick¹ c8 c8 \tick² c8 }
HTH,
Harm
