Lilyponders,
The override take effect for bar 2 to bar 4. I try to use \remove , but not working.
\version "2.19.83"
{
\fixed c' { c'4 b a g %bar 1
\override NoteHead.style = #'slash
\override Stem.transparent = ##t
\override Flag.transparent = ##t
c'4 4 4 4 %bar 2
b4 4 4 4 %bar 3
% how can I restore to default - same as bar 1
c'4 b a g %bar 4
}
}
