Hi,
In the following code, I want to rotate custom note head. To my suprise, this
code makes the whole page rotated if there is a line break. What I'm I doing
wrong?
#(define nhg
(lambda (grob)
(if
(= 2
(ly:grob-property grob 'duration-log))
(begin
(let*
((stem
(ly:grob-object grob 'stem))
(stem-dir
(ly:grob-property stem 'direction))
(rot
(if
(= stem-dir 1) 0 180)))
(ly:grob-set-property! grob 'stencil
(grob-interpret-markup grob
(markup #:rotate rot #:musicglyph "noteheads.u2doThin"))))))))
\layout {
\context {
\Staff
\override NoteHead.stencil = #nhg
}
}
{
c''4 c''4 c''4 c''4
c''4 c''4 c''4 c''4
c''4 c''4 c''4 c''4
c''4 c''4 c''4 c''4

}
