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.
How about changing \Staff into \Voice?
\layout {

That way, it won't affect those NullVoice contexts.

But your answer makes more sense to me and is what I really want to go

This?
\version "2.23.10"
\new Voice = voice {

Note that you no longer need \bar "" with \break in 2.23.10.
You should add \bar "" in 2.22.

The example has only one voice in each staff, and it probably ought
to mention that the same method should be applied to all voices.
So the answer is that every Voice must have its own grace note or skip.

Any voice that doesn't contain the grace duration will draw another
barline in the wrong place. In your case, lh_one still lacked it.

Adding more structure overcomplicates it. All you need in lh_one is:
\grace s8 a4\rest 2 q4 | % m10
similar to rh_two.

I'm merely transcribing what I see on paper as accurately as I can. Since
it didn't show any vocal line until the ninth measure (immediately after a
break) it seemed like the "right" thing to do.
%
\new Staff \with {
\RemoveAllEmptyStaves
}
%
did the trick (along with the afore-mentioned "\bar" and "\break' at the
end of the "short" measure at the end of the piano "solo" introduction and
before the partial measure where the voice starts.

Someone else brought up "French". I'd never heard of it til it was
mentioned in a response but it's good to know the terms, even if I'm not
doing symphonic stuff, just simple folk melodies and occasionally acoustic
rock.

So, I haven't been reading e-mail as quickly as normal. You've interpreted what I meant exactly, but I managed to figure out that adding a \bar was required. I had the \break but that wasn't enough.
Error message using AikenHeads with NullVoice
I have a collection of SATB hymns that I would like to engrave using shape

Re: grace note (first note) in a measure that follows an end of a repeat volta displays weirdly
Hi Hans;
Thank you. I thought I had done that :-( I had placed the grace
note with the skip in lh_two, but apparently it had no effect
I placed a << {} \\ {} >> construct in the lh_one bar 10 containing
the grace note with the skip and it works.
Wow, intricate little bug, eh? Guess it might have worked if I had
used specified voices AND the grace skip(s).
Thanks,
Ken
