When I use Baroque NoteHeads, noteheads in (temporary) different voices refuse to merge--unless I specifically create a new voice context for both voices (not just one as in the Temporary polyphonic passages example https://lilypond.org/doc/v2.22/Documentation/notation/multiple-voices#single_002dstaff-polyphony ).----- \version "2.20.0" \new Voice { \relative c'' { \override NoteHead #'style = #'baroque << % \new Voice { \voiceOne a b c } \new Voice { \voiceTwo a g c } } } ----- I.e., commenting out Baroque NoteHeads OR uncommenting \new Voice will both give the desired output, but the code as-is duplicates noteheads.
The problem is that your second voice created with \new Voice
does not actually have baroque note heads, as you can see if
you add a \breve note. This is because you use
\override NoteHead.style = #'baroque
(N.B. this is the newer syntax, NoteHead #'style is deprecated
with recent versions), and this overrides NoteHead.style in the
current Voice, not in other Voice contexts you create. If you
want to override the style more generally than in the current
Voice, you need to tell this to LilyPond with, for example,
\override Staff.NoteHead.style = #'baroque
Giving
\version "2.22.2"
\new Voice {
\relative c'' {
\override Staff.NoteHead.style = #'baroque
<<
{ \voiceOne a b c }
\new Voice { \voiceTwo a g c c }
>>
}
}
It "works" with an extra \new Voice because then both voices
have default (non-baroque) heads, whereas without that
\new Voice, the voice you started at the beginning continues
into the << >> construct. Then you have note heads with different
styles, which is the reason why LilyPond refuses to merge them.
Best,
Jean
