Re: ties, polyphony and \alternative

[Mats Bengtsson]

A tie can only occur between two notes in the same voice, which
in the world of LilyPond means that they have to live in the
same Voice context. Either you could include the full \repeat
and \alternative within one of the <<{...} \\ {...}>> voices
(actually you want at least the \repeat to appear in both voices
in that case), or you could name the contexts. Contexts with the
same name are interpreted as one and the same context.
For the latter alternative, do someting like:

\context Voice = mainVoice {
\time 6/8 \key d \major
\repeat volta 2 {
    ...
    r8 << \context Voice = mainVoice { a8[ a] a16[ d8. d16 d]~ } \\ { 
a8[ a] a16[ d8. d16 d]~ } >>
  ...
