Hello Leo,
Thanks for your explanation. Got your point, totally agree it should not
combine when 2 voices are identical, otherwise it's confusing: cannot
distinguish 2 voices.
But when I use different font-sizes to distinguish 2 voices, I can only
combine them when 2 voices are on same side of one another.
If 2nd voice goes both upper and lower than 1st one, I cannot combine them.
I found a trick, not nice, but at least works for this case: skip
exceptional note of 2nd voice, and render it on 1st voice with tweak
(I know this won't work if baritone has a separate lyrics, and here midi is
not correct either. Fortunately these are not my case ^^)
\version "2.22.1"
localFontSize =
#(define-music-function (font-size music) (number? ly:music?)
(for-some-music
(lambda (m)
(if (music-is-of-type? m 'rhythmic-event)
(begin
(set! (ly:music-property m 'tweaks)
(cons `(font-size . ,font-size)
(ly:music-property m 'tweaks)))
#t)
#f))
music)
music)
soprano = { f'4 g'4 a'4 b'4 c''2 }
basso = { d'4 e' f'' g' a'2 }
alto = { d'4 e' \stemUp f'' g' a'2 }
tenor = { d'4 e' f'' g' a'2 }
\new Score { \new Staff << \partCombine \soprano \basso >> } % correct but
not expected
\new Score { \new Staff << \partCombine \soprano \alto >> } % expected,
without tweak, can combine but cannot confusing
\new Score { \new Staff << \partCombine \soprano \localFontSize -3 \tenor
>> } % distinguish 2 voices, but not combined
mezzo = { f'4 g'4 <a' \tweak font-size #-3 f''>4 b'4 c''2 }
baritone = { d'4 e' \skip 4 g' a'2 }
\new Score { \new Staff << \partCombine \mezzo \localFontSize -3 \baritone
>> } % trick
Thanks to all.
Have a good day.
Tu'
