<h3 class="subsection">3.1.1 Structure of a score</h3>
<a name="index-_005cscore"></a>
<a name="index-_005cscore-1"></a>
<p>A <code>\score</code> block must contain a single music expression
delimited by curly brackets:
</p>
<blockquote><pre class="example">\score {
...
}
</pre></blockquote>
<table class="cartouche" border="1"><tr><td>
<p><b>Note:</b> There must be <strong>only one</strong> outer music expression in
a <code>score</code> block, and it <strong>must</strong> be surrounded by
curly brackets.
</p></td></tr></table>
<p>This single music expression may be of any size, and may contain
other music expressions to any complexity. All of these examples
are music expressions:
</p>
<blockquote><pre class="example">{ c'4 c' c' c' }
</pre></blockquote>
<blockquote><pre class="verbatim">{
{ c'4 c' c' c'}
{ d'4 d' d' d'}
}
</pre><p>
<a href="../24/lily-b6134979.ly">
<img align="middle"
border="0"
src="../24/lily-b6134979.png"
alt="[image of music]">
</a>
</p>
</blockquote>
<blockquote><pre class="verbatim"><<
\new Staff { c'4 c' c' c' }
\new Staff { d'4 d' d' d' }
>>
</pre><p>
<a href="../1a/lily-0f5d4dab.ly">
<img align="middle"
border="0"
src="../1a/lily-0f5d4dab.png"
alt="[image of music]">
</a>
</p>
</blockquote>
<blockquote><pre class="example">{
\new GrandStaff <<
\new StaffGroup <<
\new Staff { \flute }
\new Staff { \oboe }
>>
\new StaffGroup <<
\new Staff { \violinI }
\new Staff { \violinII }
>>
>>
}
</pre></blockquote>
<p>Comments are one exception to this general rule. (For others see
<a href="File-structure.fr.html#File-structure">File structure</a>.) Both single-line comments and comments
delimited by <code>%{ .. %}</code> may be placed anywhere within an
input file. They may be placed inside or outside a <code>\score</code>
block, and inside or outside the single music expression within a
<code>\score</code> block.
