Re: Reconnecting voices in Lilypond

[Mats Bengtsson]

Did you try to just add the slur in the existing example?
As long as there are no notes between the two << ... \\ ... >>,
you can do
  <<
     a4(
    \\
     b4
  >>
  <<
    c4)
    \\
    d4
  >>

Since the two Voice contexts created by this construct are called
"1" and "2", respectively, the both ends of the slur will actually
appear in the same Voice context, so it works.

If you have some music between the chords, these temporary contexts
will not survive the gap, but you can make it work using the following
trick:
\version "2.2"
\score{
\new Staff\notes\relative c' <<
\context Voice = "1" {s1*2}
\context Voice = "2" {s1*2}
\new Voice {
 c4 d e f
<<
     a(
    \\
     b
  >>
  c
  <<
    c)
    \\
    d
  >>
}
>>
}

The purpose of the \context Voice = "1" {s1*2} is just to keep the
voice alive long enough.
