In [[13-limit]] [[Just Intonation]], 13/11 is the tridecimal minor third (or [[Neo-Gothic]] minor third), measuring about 289.2¢. It is the difference between the 11th and 13th harmonics. The (octave-reduced) 11th harmonic ([[11_8|11/8]], about 551.3¢) and 13th harmonic ([[13_8|13/8]], about 840.5¢) are both quite xenharmonic and demand new interval categories, while 13/11 can be likened unto some kind of relatively complex minor third. It can even function as such in a 13-limit Neo-Gothic minor triad of 22:26:33, with a [[3_2|3/2]] perfect fifth between 33 and 22. Compare this to 22:26:32 (11:13:16), which has the much more dissonant [[16_11|16/11]] as the outside interval in place of 3/2. The latter triad sounds more like a xenharmonic version of a diminished triad, and could not be confused with simpler diminished triads such as 5:6:7.

13/11 is the classic [[mediant]] between the simpler and more familiar ratios [[6_5|6/5]] and [[7_6|7/6]], as it can be given as (6+7)/(5+6). This puts in between the latter ratios, slightly closer to 7/6. More complex minor thirds can be generated by taking the mediant between 13/11 and 7/6 (which yields (13+7)/(11+6) = [[20_17|20/17]], the septendecimal subminor third, about 281.4¢) and between 13/11 and 6/5 (which yields (13+6)/(11+5) = [[19_16|19/16]], the overtone minor third of [[19-limit]] JI, about 297.5¢). (See the diagram below.)

13/11 is also [[352_351|352/351]] (about 4.9¢) narrower than [[32_27|32/27]], the minor third in Pythagorean ([[3-limit]]) tuning.

Compare this to 22:26:32 (11:13:16), which has the much more dissonant &lt;a class="wiki_link" href="/16_11"&gt;16/11&lt;/a&gt; as the outside interval in place of 3/2. The latter triad sounds more like a xenharmonic version of a diminished triad, and could not be confused with simpler diminished triads such as 5:6:7.&lt;br /&gt;

+In &lt;a class="wiki_link" href="/13-limit"&gt;13-limit&lt;/a&gt; &lt;a class="wiki_link" href="/Just%20Intonation"&gt;Just Intonation&lt;/a&gt;, 13/11 is the tridecimal minor third (or &lt;a class="wiki_link" href="/Neo-Gothic"&gt;Neo-Gothic&lt;/a&gt; minor third), measuring about 289.2¢. It is the difference between the 11th and 13th harmonics. The (octave-reduced) 11th harmonic (&lt;a class="wiki_link" href="/11_8"&gt;11/8&lt;/a&gt;, about 551.3¢) and 13th harmonic (&lt;a class="wiki_link" href="/13_8"&gt;13/8&lt;/a&gt;, about 840.5¢) are both quite xenharmonic and demand new interval categories, while 13/11 can be likened unto some kind of relatively complex minor third. It can even function as such in a 13-limit Neo-Gothic minor triad of 22:26:33, with a &lt;a class="wiki_link" href="/3_2"&gt;3/2&lt;/a&gt; perfect fifth between 33 and 22. Compare this to 22:26:32 (11:13:16), which has the much more dissonant &lt;a class="wiki_link" href="/16_11"&gt;16/11&lt;/a&gt; as the outside interval in place of 3/2. The latter triad sounds more like a xenharmonic version of a diminished triad, and could not be confused with simpler diminished triads such as 5:6:7.&lt;br /&gt;
 &lt;br /&gt;
 /11 is the classic &lt;a class="wiki_link" href="/mediant"&gt;mediant&lt;/a&gt; between the simpler and more familiar ratios &lt;a class="wiki_link" href="/6_5"&gt;6/5&lt;/a&gt; and &lt;a class="wiki_link" href="/7_6"&gt;7/6&lt;/a&gt;, as it can be given as (6+7)/(5+6). This puts in between the latter ratios, slightly closer to 7/6. More complex minor thirds can be generated by taking the mediant between 13/11 and 7/6 (which yields (13+7)/(11+6) = &lt;a class="wiki_link" href="/20_17"&gt;20/17&lt;/a&gt;, the septendecimal subminor third, about 281.4¢) and between 13/11 and 6/5 (which yields (13+6)/(11+5) = &lt;a class="wiki_link" href="/19_16"&gt;19/16&lt;/a&gt;, the overtone minor third of &lt;a class="wiki_link" href="/19-limit"&gt;19-limit&lt;/a&gt; JI, about 297.5¢).
