Lyrics in Notation Reference

Guy Stalnaker requested an enhancement to the docs here:

http://lists.gnu.org/archive/html/bug-lilypond/2013-03/msg00052.html

as follows:

Add to this page after the section for Divisi lyrics at the bottom:

http://lilypond.org/doc/v2.16/Documentation/notation/techniques-specific-to-lyrics

The following is based on this page for Temporary polyphonic passages.

http://lilypond.org/doc/v2.16/Documentation/notation/multiple-voices

Addition:

It is common in choral music to have a voice part split for a cadence, or a  
measure or two. The << {...} \\ {...} >> construct, where the two (or more)  
musical expressions are separated by double backslashes, might seem the  
proper way to set the split voices. This construct, however, will assign  
*all* the expressions within it to *NEW Voice contexts* which will result  
in *no lyrcis* being set for them since the lyrics will be set to the  
original voice context--not, typically, what one wants. The temporary  
polyphonic passage is the proper construct to use.

The temporary polyphonic passage construct format is:

<code>

<< { \voiceOne ... }
  \new Voice { \voiceTwo ... }
\oneVoice

</code>

Note the absence of \\ after \voiceOne! The first expression within a  
temporary polyphonic passage is placed into the Voice context which was in  
use immediately before the polyphonic passage, and that same Voice context  
continues after the temporary section. Other expressions within the angle  
brackets are assigned to distinct temporary voices. This allows lyrics to  
be assigned to one continuing voice before, during and after a polyphonic  
section, but not the temporary voices.

The following example shows how to create a temporary polyphonic  
(multi-voice) passage that will also set lyrics. If you normally create  
voice and lyrics variables then construct the score using those variables,  
the lyrics for a voice using this temporary polyphonic passage construct  
will be set following \voiceOne.

<code>

verse = \lyricmode {

  %Verse one snippet
  Est et in -- ef --

  fa -- bi -- lis

  In di -- vi -- ni --

  ta -- te.

  %Verse two ending

  An -- ti -- que de --

  e --

  rum.

}

bass = {

  \key f \major

  \time 4/4

  \repeat volta 2 {

    g,4 g, bf, bf, |

    a, bf, c2 |

  }

  \alternative {

    { %First ending

      c4 c bf, bf, |

      c2 c

    }

    { %Second ending

<<

{ \voiceOne c4 c f f | ef2( df) | c1 }

{ \new Voice { \voiceTwo c4 c bf, g, | f,1 | f,1 \fermata } }

> > | \voiceOne

}

}\bar "|."


}

bassPart = \new Staff

{ \clef bass \bass }

\addlyrics { \verse }

\score {

  <<

    \bassPart

  >>

  \layout { }

  \midi { }

}

</code>

Best regards,

Guy
