Re: Square note head style

[Pierre Perol-Schneider]

Hi Caio,

How about:

\version "2.18.2"

#(define (my-note-head grob)
   (let ((duration (ly:grob-property grob 'duration-log)))
     (if (>= duration 2)
         (grob-interpret-markup grob
              #{
                \markup \filled-box #'(-0.5 . 0.5) #'(-0.5 . 0.5) #0
              #})
         (grob-interpret-markup grob
                #{
                  \markup
                  \override #'(box-padding . 0)
                  \override #'(thickness . 2)
                  \box {
                    \transparent
                    \filled-box #'(-0.3 . 0.3) #'(-0.3 . 0.3) #0
                  }
                #}))))

{ c'1 c'2 c'4 c'8 c'16 }

\layout {
  \context {
    \Score
    \override NoteHead.stencil = #my-note-head
  }
}

Cheers,

Pierre

Hi,

I'm needing a note head style with square note heads. Ideally it should be filled for black note heads and open for white notes. I'm struggling to understand how to change the note head stencil, let alone change it according to note duration. Con someone, please, help?

Thanks!
Caio
