Bar lines and bar numbers are calculated automatically. For
unmetered music (some cadenzas, for example), this is not desirable.
To turn off automatic calculation of bar lines and bar numbers,
use the command <code>\cadenzaOn</code>, and use <code>\cadenzaOff</code>
to turn them on again.
<blockquote>
<pre class="verbatim">
c4 d e d
\cadenzaOn
c4 c d8 d d f4 g4.
\cadenzaOff
\bar "|"
d4 e d c
</pre>

<img align="middle"
border="0" src="../33/lily-e81e42ef.png" alt="[image of music]">
</a>
</p>
</blockquote>
<p>Bar numbering is resumed at the end of the cadenza as if the
cadenza were not there:
<blockquote>
<pre class="verbatim">
% Show all bar numbers
\override Score.BarNumber #'break-visibility = #all-visible
c4 d e d
\cadenzaOn
c4 c d8 d d f4 g4.
\cadenzaOff
\bar "|"
d4 e d c
</pre>

<h5 class="subsubheading">Known issues and warnings</h5>
<p>LilyPond will insert line breaks and page breaks only at a
bar line. Unless the unmetered music ends before the end of the
staff line, you will need to insert invisible bar lines with
<pre class="example">\bar ""
</pre>
<p class="noindent">to indicate where breaks can occur.
