<h2 class="chapter">4 Spacing issues</h2>
<p>The global paper layout is determined by three factors: the page layout, the
line breaks, and the spacing. These all influence each other. The
choice of spacing determines how densely each system of music is set.
This influences where line breaks are chosen, and thus ultimately, how
many pages a piece of music takes.
<p>Globally speaking, this procedure happens in four steps: first,
flexible distances (‘springs’) are chosen, based on durations. All
possible line breaking combinations are tried, and a ‘badness’ score
is calculated for each. Then the height of each possible system is
estimated. Finally, a page breaking and line breaking combination is chosen
so that neither the horizontal nor the vertical spacing is too cramped
or stretched.
<p>Settings which influence layout may be placed in two blocks.
The <code>\paper {...}</code> block is placed outside any
<code>\score {...}</code> blocks and contains settings that
relate to the entire document. The <code>\layout {...}</code>
block is placed within a <code>\score {...}</code> block and
contains settings for that particular score. If you have
only one <code>\score {...}</code> block the two have the same
effect. In general the commands shown in this chapter can
be placed in either.
