<div style="width:100%; max-height:400pt; overflow:auto; background-color:#f8f9fa; border: 1px solid #eaecf0; padding:0em"><pre style="margin:0px;border:none;background:none;word-wrap:break-word;width:200%;white-space: pre-wrap ! important" class="old-revision-html">&lt;html&gt;&lt;head&gt;&lt;title&gt;Quarter-comma meantone&lt;/title&gt;&lt;/head&gt;&lt;body&gt;Quarter comma meantone is the tuning of &lt;a class="wiki_link" href="/Meantone%20family"&gt;meantone temperament&lt;/a&gt; which makes the fifth the fourth root of 5, or in other words 696.578 cents. This means the fifth is flattened by 1/4 of the syntonic comma (81/80 ratio) of 21.506 cents, which is to say by 5.377 cents, hence the name quarter-comma or 1/4-comma meantone. It is also the tuning where the major tone is the exact geometric mean between the greater tone of 9/8 and the lesser tone of 10/9, and hence it can be argued it is the only tuning which is strictly &amp;quot;mean tone&amp;quot;. It is the minimax tuning for 5-limit meantone, meaning the maximum error on the 5-limit &lt;a class="wiki_link" href="/Diamonds"&gt;diamond&lt;/a&gt; is minimized. It is also the minimax tuning for septimal meantone in the 7- and 9-limit odd limits, and for meanpop, the version of 11-limit meantone which tunes 11/8 to the doubly diminished fifth, C-Gbb. Moreover, historically it was the predominant tuning of Western common-practice music in the latter part of the Renaissance and the early modern (17th century) era.&lt;br /&gt;

Because of all of these features, it has a certain claim to be considered the canonical meantone tuning and often &amp;quot;meantone&amp;quot; is taken to mean quarter-comma specifically. The traditional interval names, listed below, may be considered to have their older traditional tuning in the quarter-comma meantone tunings listed below. However, other tunings (besides &lt;a class="wiki_link" href="/12edo"&gt;12edo&lt;/a&gt; which is ubiquitous but not an especially good tuning for meantone) may be preferred. Note, for instance, that the doubly augmented second and the doubly diminished fourth are both neutral thirds, about six cents apart. If we want a tuning which will equate the two, we need to use &lt;a class="wiki_link" href="/31edo"&gt;31edo&lt;/a&gt; instead.&lt;br /&gt;

&lt;br /&gt;

  Below is a table listing 36 of the notes of quarter-comma meantone, giving the size in cents, the number of fifths up or down on the &lt;a class="wiki_link" href="/chain%20of%20fifths"&gt;chain of fifths&lt;/a&gt;, the &lt;a class="wiki_link_ext" href="http://en.wikipedia.org/wiki/Letter_notation" rel="nofollow"&gt;letter notation&lt;/a&gt; for the interval relative to C as the tonic, the traditional name for the interval, a shorthand form of the name, and the size of the interval in &lt;a class="wiki_link" href="/Fractional%20monzos"&gt;fractional monzo&lt;/a&gt; notation.&lt;br /&gt;

&lt;br /&gt;
