Minimal examples (was: Last number on a score; but this is the first in the next one...)

I’ll show you how this can be simplified.

You don’t need an empty \header, \paper, \layout, … block.

Clef, key, time signature style don’t have anything to do with your
problem. Omit them.

Try less notes, and if you want multiple lines of music with little
input, try R1*20 or \repeat unfold 20 a1 or something like that. Apart
from that your comments are neither bar nor line numbers so why are they
there?

You don’t need that bar line.

You don’t need a score block if there is only one score in your lilypond
file.

Instrument names have nothing to do with your problem.

You are already in a Staff context, why state that explicitely again?
And why name your Voice if you don’t have \change commands or \lyricsto
or something similar?

You don’t need that unless you have some content in this \layout block
or an additional \midi block.

This gives the following almost-minimal example:

%%% BEGIN
\version "2.18.2"

PartPOneVoiceOne =  \relative a' {
  \override Score.BarNumber.break-visibility = #'#(#t #t #t)
  R1*20
}

\new Staff \PartPOneVoiceOne
%%% END

Why almost minimal? Because you don’t need the \new Staff (a staff
created anyway) and your example is so small that you don’t need a
variable definition and usage. Oh, and of course without notes you don’t
need \relative. So here comes a truly minimal working example:

%%% BEGIN
\version "2.18.2"

{
  \override Score.BarNumber.break-visibility = #'#(#t #t #t)
  R1*20
}
%%% END

Why not omit the version number making this even smaller? Because nobody
has to ask which version you use then :)

Of course it’s not a problem to have a small example that’s not truly
minimal. But your example had 22 lines, mine has 6 (if you count empty
lines) and in so few lines you don’t first have to find out which lines
are relevant for the problem and which are not.
