The (lesser) neutral second is a strangely exotic interval found between the 11th and 12th partials of the harmonic series. In Just Intonation it is represented by the [[superparticular]] ratio 12/11, and is about 150.6 [[cent|cents]] large. One step of [[8edo]] is an excellent approximation of the just neutral second, and eight of them exceed the octave by the comma (12/11)^8/2 = |15 8 0 0 -8&gt;. It follows that EDOs which are multiples of 8, such as [[16edo]] and [[24edo]], will also represent this interval well.

12/11 differs from the larger undecimal neutral second 11/10 (~165 cents) by 121/120 (~14.4 cents). Temperaments which conflate the two (thus tempering out 121/120) include [[15edo]], [[22edo]], [[31edo]], [[orwell]], [[porcupine]], [[mohajira]] and [[valentine]].</pre></div>

The (lesser) neutral second is a strangely exotic interval found between the 11th and 12th partials of the harmonic series. In Just Intonation it is represented by the &lt;a class="wiki_link" href="/superparticular"&gt;superparticular&lt;/a&gt; ratio 12/11, and is about 150.6 &lt;a class="wiki_link" href="/cent"&gt;cents&lt;/a&gt; large. One step of &lt;a class="wiki_link" href="/8edo"&gt;8edo&lt;/a&gt; is an excellent approximation of the just neutral second, and eight of them exceed the octave by the comma (12/11)^8/2 = |15 8 0 0 -8&amp;gt;. It follows that EDOs which are multiples of 8, such as &lt;a class="wiki_link" href="/16edo"&gt;16edo&lt;/a&gt; and &lt;a class="wiki_link" href="/24edo"&gt;24edo&lt;/a&gt;, will also represent this interval well.&lt;br /&gt;
