Re: devnull with lyrics and ties

[Walt North]

thanks.   So far no luck.   I'm giving up for the night.  Get back it tomorrow.  Here is what I have tried so far.

\version "2.24.2"

\language "english"

\layout {
  indent = 0
  \context {
    \NullVoice
    \RemoveAllEmptyStaves
  }
  \context {
    \Score
    \accepts NullVoice
  }
  \context {
    \Staff
    \accepts NullVoice
  }
}

verseLyricsMelody = \relative c' {
  c4 c c c~ | c c c c |
}

verseOneLyrics = \lyricmode {
  one two three four five six seven eight
}

\new Score {
  \new Staff
  <<
    <<
      \new NullVoice  = "verseA" { \break  \verseLyricsMelody }
      \new Lyrics \lyricsto "verseA" { \verseOneLyrics }
    >>
  >>
}

\new Score {
  \new Staff
  <<
    <<
      \new NullVoice  = "verseB" { \break  \verseLyricsMelody }
    >>
    \new Lyrics \lyricsto "verseB" { \verseOneLyrics }
  >>
}

Another way to get the extra Staff not to appear is to add the following to your \layout block:

  \context {
    \Score
    \accepts NullVoice
  }

As an aside directed more at the dev community: is there any good reason not to make this the default behavior (and similar for StaffGroup, etc.)? NullVoice is defined with both Staff and Voice as aliases. I would have assumed this meant that it could be used anywhere that Staff could be used.

The easiest way to get the staff not to appear would be to put NullVoice inside a Staff or similar context that you want to appear.

Thanks, that took care of the alignment. 

However now I see an empty staff.  Is it expected I would then have to remove all empty staves?  I tried that but may not have it right

\version "2.24.2"

\language "english"

\layout {
  indent = 0
  \context {
    \NullVoice
    \RemoveAllEmptyStaves
  }
}

verseLyricsMelody = \relative c' {
  c4 c c c~ | c c c c |
}

verseOneLyrics = \lyricmode {
  one two three four five six seven eight
}

\new Score {
  <<
    \new Voice = "verse" { \break \verseLyricsMelody }
    \new Lyrics \lyricsto "verse" { \verseOneLyrics }
  >>
  <<
    \new NullVoice  = "verseB" { \break  \verseLyricsMelody }
    \new Lyrics \lyricsto "verseB" { \verseOneLyrics }

  >>

}

My understanding is that Devnull is not intended for alignment of lyrics because it does not have the necessary engraver to create the invisible grobs used for alignment. It appears to me in your example that actually the lyrics are just being spaced evenly without alignment to anything. Nullvoice is intended for your use case.

Am I missing something?  It seems like using devnull to align lyrics to does pay attention to ties.  Ties do seem to be honored when using voice for alignment.

Below is a stripped down example with screenshot.

\version "2.24.2"

\language "english"

\layout {
  indent = 0
}

verseLyricsMelody = \relative c' {
  c4 c c c~ | c c c c |
}

verseOneLyrics = \lyricmode {
  one two three four five six seven eight
}

\new Score {
  <<
    \new Voice = "verse" { \break \verseLyricsMelody }
    \new Lyrics \lyricsto "verse" { \verseOneLyrics }
  >>
  <<
    \new Devnull  = "verseB" { \break  \verseLyricsMelody }
    \new Lyrics \lyricsto "verseB" { \verseOneLyrics }
  >>
}
