Re: Tie doesn't tie

[Kieren MacMillan]

Hi Erik,

> Why doesn't the first bar tie to the second?

Because there are three different Voice contexts involved here... be  
sure to read the documentation, especially
<http://lilypond.org/doc/v2.13/Documentation/notation/Multiple- 
voices#Multiple-voices>

But you don't even need that much explanation — you simply need to  
put the first chord of the tied set outside the <<>>, e.g.

mus = \relative c {
  \autoBeamOff
  \key d \major
  \time 3/4
  \clef bass
  << { <d a' d>2 } \\ { d,2 } >> <d d'>4 ~   |
  <d d'>2.   |
}

\score { \mus }

Hope this helps,
Kieren.
