It contains a list <code>break-align-symbol</code>s with a specification of the associated space. The space specification can be <dl> <dt><code>(minimum-space . </code><var>spc</var><code>))</code><dd>Pad space until the distance is <var>spc</var>. <br><dt><code>(fixed-space . </code><var>spc</var><code>)</code><dd>Set a fixed space. <br><dt><code>(semi-fixed-space . </code><var>spc</var><code>)</code><dd>Set a space. Half of it is fixed and half is stretchable. (does not work at start of line. fixme) <br><dt><code>(extra-space . </code><var>spc</var><code>)</code><dd>Add <var>spc</var> amount of space. </dl> <p>Special keys for the alist are <code>first-note</code> and <code>next-note</code>, signifying the first note on a line, and the next note halfway a line. <p>Rules for this spacing are much more complicated than this.
