Re: Tie running through stems

[Mats Bengtsson]

What version of LilyPond do you use? Please always state that, or even
better, include a
\version "2.4.2"
line at the top of your .ly code.

The problem you see is not a bug in the implementation, but a lack of
documentation. As is described at
http://lilypond.org/doc/v2.4/Documentation/user/out-www/lilypond/Writing-polyphonic-music.html#Writing-polyphonic-music
the <<{...} \\ {...}>> feature implicitly sets properties of the upper
and lower voice corresponding to the \voiceOne and \voiceTwo macros.
What's not described is exactly what these macros do, namely that
\voiceOne set the direction of stems, slurs, ties, articulations,
text annotations, dots of dotted notes and fingerings to point upwards,
whereas \voiceTwo makes the same list of object be directed downwards.
The intention, of course, is to make it as clear as possible what notes
belong to which voice, even when the voices cross.
