I have a collection of SATB hymns that I would like to engrave using shape
notes. The Lilypond files are all structured the same, as seen below—treble
clef with music and a NullVoice for aligning lyrics, then the lyrics, then the
bass clef.
%%%%%
\version "2.22"
\language “english"
% included from another file
\layout {
\context {
\Staff
\aikenHeads
}
}
\score {
<<
\new Staff <<
% music here
\new NullVoice = "melody" { e'8 fs'8 }
>>
% \new Lyrics \lyricsto "melody" { Ly -- rics }
% bass clef here
>>
\layout {}
}
%%%%%
The command to use aikenHeads comes from a separate style file that gets
included for each hymn. But there is an unfortunate interaction between
aikenHeads and NullVoice: Lilypond outputs the following error message:
programming error: must have stem dir for note head
continuing, cross fingers
And it outputs a lot of these messages. I need to find a way to stop Lilypond
from outputting this error. Any kind of quick fix or hack would be sufficient.
One thought I had would be to re-enable regular note heads for the NullVoice:
\new NullVoice = "melody" \with { \unset shapeNoteStyles } { e'8
fs'8 }
But I couldn’t come up with anything that worked.
Any help or ideas would be greatly appreciated.
