Hi Dan!

The disease is that Lilypond needs to see lyrics for multiple stanzas encoded as simultaneous music in order to set them one below another, and the right action is to cure that, not to infect \repeat. 


Well, at least it is possible to define lyrics within a stanza in a way to 
produce the correct results with bold unfold and not unfolded repeats.

\version "2.21.0"

melody = { \relative { \repeat volta 2 { c''4 4 4 4 } \alternative { { d2 2 } { 
e2 2 } } c1 } }
lyricA = \lyricmode { \repeat volta 2 { a a a a } \alternative { { b b } { c c 
} } d }
lyricB = \lyricmode { \repeat volta 2 { e e e e } \alternative { { f f } { g g 
} } h }


{
    { \melody \bar "|." }
    \addlyrics { \set stanza = #"1. " \lyricA }
    \addlyrics { \set stanza = #"2. " \lyricB }
}


\unfoldRepeats {
    { \melody \bar "|." }
    \addlyrics { \set stanza = #"1. " \lyricA }
    \addlyrics { \set stanza = #"2. " \lyricB }
}

%
% Do you look for a function named e.g \unfoldStanzas to be used like e.g.
%
%   \unfoldStanzas \unfoldRepeats {
%   { \melody \bar "|." }
%   \addlyrics { \set stanza = #"1. " \lyricA }
%   \addlyrics { \set stanza = #"2. " \lyricB }
%   }
%
% that should produce something like
%

\unfoldRepeats {
    { \melody \bar "||" \melody \bar "|." }
    \addlyrics { \lyricA \lyricB }
}

I don't think that such a function would be very useful, think about dynamics 
etc.

I find the metaphor slightly too strong, since I think the ‘cure’ is 
merely in devising an intuitive input method. IMO it should take the 
text in order as input and rearrange it into one \markup \column {} per 
(syllable*repeat number), _and_ place brackets at the beginning and end 
of repeats as required. I’d love to have time for writing such a music 
function[1]…


Best, Simon

[1] the bracket part is more complicated, since the closing brackets 
would actually require something like ‘afterStanza’, if you get what I mean…

I meant what I wrote, but I take your point and Carl's.  The disease is that 
Lilypond needs to see lyrics for multiple stanzas encoded as simultaneous music

not to infect \repeat.

As several people have pointed out, this is not a repeat. It is the
notes in \A doubled in unison followed by \B played at the same time
as \C.

Perhaps Dan meant the following?

<<
{ \A \A }
{ \B \C }
>>

Here, \A is repeated (so there is repetiton) but played against \B the
first time and against \C the second time (provided, of course, that
\A and \B have the same duration).

If so, it would be the same as

<<
{ \repeat volta 2 { \A } }
{ \B \C }
>>

Not even as

  \alternative {
\new Lyrics { \stanzaI }
\new Lyrics { \stanzaII }
  }

to be treated as simultaneous during engraving but unfolded before performing?

Repeats result in sequential music, regardless of whether they are volta, 
unfold, or tremolo, right?

There are no repeats named by that structure that I am aware of in the music 
literature that create simultaneous music.

If we want to do something like this I think we should call it a lyricrepeat, 
or a stanzarepeat.

But the most common stanza repeat stuctire in my experience is a verse-chorus 
structure:

\stanzarepeat \stanzas { \new lyrics {\stanza1}{\stanza2}{\stanza3}} {\chorus}

Consider: \repeat XX \A \alternative { \B \C }

If “unfold” is effectively

   {
 { \A \B }
 { \A \C }
   }

what type would you call this, if it existed?
