RE: once again with a header, tie into polyphony question
Ole
Notes in different voices cannot be tied together. The
notes in your first chord are in the default voice whereas
the second d is in the voice called 1. As the d and fis
in the second bar have different durations yet start at the
same time they cannot be placed in the same voice. So you
have to place the notes in the first chord in different
voices too. If the polyphony is of short duration this is
the easiest way:
\new Staff
\time 3/4
\relative c' {
r4
{ fis2~ } \\ { d2~ } |
{ fis8. d'16 } \\ { d,4 }
r2 |
}
but if the polyphony is much longer it may be better to
explicitly instantiate the voices:
\new Staff
\time 3/4
\new Voice = 1 {
\voiceOne
\relative c' {
r4 fis2~ |
fis8. d'16 r2 |
}
}
\new Voice = 2 {
\voiceTwo
\relative c' {
s4 d2~ |
d4 s2 |
}
}
(note the different octave specification on the d4 as the
relative positions in the input are different in the two
approaches)
Both of these methods cause the stems on the first d2 to
point down. This can be fixed if you really want them up.

Dear all,
I want to have both of the first two notes tied
-the d and the f-
sharp. How do I achieve that?
Thanks for a hint

The problem is, that the Tie_engraver - that generates ties - lives at
voice level. That means that the Tie_engraver can only see notes in
the same voice - and therefore cannot tie notes from different voices
together.
The reason why the engraver does not live at Staff level is that this
would make ties in polyphony impossible. If you for instance have
e4 ~ e8 e8
//
c8 c8 ~ c4
Then - if the Tie_engraver were living at Staff level - it would see e
followed by c followed by e. Therefore the two e's that you try to tie
together would not be seen as neighbours, and the engraver would be
confused and produce bad results.
If you really REALLY really need to tie different voice together then
you can add the tie-engraver to BOTH staff and voice. And manually make
the ties that you are not interested in invisible.
It goes like this:
%%% BEGIN %%%
\version 2.10.25
\layout {
\context {
\Staff
\consists Tie_engraver
\override Tie #'transparent = ##t
}
\context {
\Voice
\override Tie #'transparent = ##f
}
}
tiesToVoice = {
\revert Staff.Tie #'transparent \override Staff.Tie #'transparent = ##t
\revert Voice.Tie #'transparent \override Voice.Tie #'transparent = ##f
}
tiesToStaff = {
\revert Staff.Tie #'transparent \override Staff.Tie #'transparent = ##f
\revert Voice.Tie #'transparent \override Voice.Tie #'transparent = ##t
}
{
\transpose c c' {
\tiesToStaff
e c 4 ~ e c 8 e c ~
{ e e e e |
\tiesToVoice
e4 ~ e8 e }
\\ { c8 c c c |
\tiesToVoice
c8 c ~ c4 }
}
}
%%% END %%%
I will add this to LSR as soon as I get the \revert \override -thing
checked. I do not understand why it cannot be replaced with \set.

Another possibility is to fake it by letting a stemless (i.e. transparent
stem) in one voice be merged with that of another: the head is still there,
and can therefore start a tie, but it appears as if the ties change from
one voice to another. Below is the first measure of Fernando Sor's Fantasie
elegiaque, which requires the notes of a grace-like arpeggio to be tied to
three different voices. It may not be the prettiest code in the world, but
at least it works
(BTW, I thought there was supposed to be something like
\override Staff.NoteCollision #'merge-differently-dotted = ##t
\override Staff.NoteCollision #'merge-differently-headed = ##t
in there, but apparently, it works)
\relative c' {
\key e\minor
\time 4/4
{
\set Staff.tieWaitForNote = ##t
\partial 64*5
\voiceOne \slurDown
a64\f fis' c'
\tieDown
dis64~ c'
\stemUp
dis, c'4..
\times 2/5 { b'32 a g fis e } dis8
}
\\
{
\voiceTwo
s64
\once \override Stem #'transparent = ##t
fis,64~
\noBeam \once \override Stem #'transparent = ##t
c'64*3~ fis, c'4..
}
\\
{
\voiceFour
\once \override Stem #'transparent = ##t
\tieDown
a,64*5 ~
\stemDown a2
}
}

It's not clear what you might have needed around this snippet but the
following works in 2.11.34
\version 2.10.15
\new Staff {
\time 3/4
\relative c' {
r4 { fis2 ~ fis8. d'16 } \\ { d,2 ~ d4 } r2 |
