Re: repeat

Excuse my replying to the wrong posting, but I can't reply to a
posting that seems to be missing from the thread.

Yes, we understand your last sentence. As you said in your OP:
"Is there the use of a repetition (repeat volta) possible to shorten
the sheet music?"

It appears from the conversation quoted above that you don't
understand the concept of a repeat: that you write/print the sequence
of notes _once_ and you play it _twice_, thereby "shortening the sheet".
Halving it, in fact.

So, if you write/print the sequence of notes once, why would you want
to copy and paste them all in again?

While we're here, I might as well reply to this bit...

I thought we came up with a reasonable rendition of this structure in
http://lists.gnu.org/archive/html/lilypond-user/2015-10/msg00404.html
(particularly where the BB sections are short) though it's not a repeat
structure as far as LilyPond is concerned, so no \repeat or
\alternative commands, and no correct MIDI rendition without juggling
the chunks in variables, ie
\score { { \AAA \BB1 \CCC \AAA \BB2 \CCC } \midi { } }

This will unnecessarily prevent LilyPond using the \repeat volta
construction and so, once again, no MIDI rendition among other
concerns, eg, what about three times through; why is only one version
written on the principal staff, others being relegated to ossias; etc.

I can't help wondering what you and the OP have against a conventional
method like those depicted in
http://lists.gnu.org/archive/html/lilypond-user/2016-02/msg00260.html
and employed in real music such as (citing just one example):
