In music, **19 equal temperament**, called 19-TET, 19-[[xenharmonic/EDO|EDO]], or 19-ET, is the scale derived by dividing the [[xenharmonic/octave|octave]] into 19 [[xenharmonic/equal|equal]]ly large steps. Each __[[#|step]]__ represents a frequency ratio of the 19th root of 2, or 63.16 [[xenharmonic/cent|cents]]. It is the 8th [[xenharmonic/prime numbers|prime]] edo, following [[xenharmonic/17edo|17edo]] and coming before [[xenharmonic/23edo|23edo]].

Interest in this tuning system goes back to the sixteenth century, when composer Guillaume Costeley used it in his chanson [[Seigneur Dieu ta pitié]] of 1558. Costeley understood and desired the circulating aspect of this tuning; in 1577 music theorist Francisco de Salinas in effect proposed it. Salinas discussed [[xenharmonic/1-3 Syntonic Comma Meantone|1/3-comma meantone]], in which the fifth is of size 694.786 cents; the fifth of 19-et is 694.737, which is only a twentieth of a cent flatter. Salinas suggested tuning nineteen tones to the octave to this tuning, which fails to __[[#|close]]__ by less than a cent, so that his suggestion is effectively 19-et. In the nineteenth century mathematician and music theorist Wesley Woolhouse proposed it as a more practical alternative to meantone tunings he regarded as better, such as [[xenharmonic/50edo|50 equal temperament]] ([[http://sonic-arts.org/monzo/woolhouse/essay.htm|summary of Woolhouse's essay]]).

The most salient characteristic of 19-et is that, having an almost just minor third and perfect fifths and major thirds about seven cents narrow, it serves as a good tuning for [[xenharmonic/Meantone family|meantone]] temperament. It is also a suitable for [[xenharmonic/Regular Temperaments#magic|magic/muggles]] temperament, because five of its major thirds are equivalent to one of its //twelfths.// For both of these there are more optimal tunings: the fifth of 19-et is flatter than the usual for meantone, and a more accurate approximation is [[xenharmonic/31edo|31 equal temperament]]. Similarly, the generating interval of magic temperament is a major third, and again 19-et's is flatter; [[xenharmonic/41edo|41 equal temperament]] more closely __[[#|matches]]__ it. It does make for a good tuning for muggles, which in 19et is the same as magic.

However, for all of these 19-et has the practical advantage of requiring fewer pitches, which makes physical realizations of it easier to build. (Many 19-et instruments have been built.) 19-et is in fact the second equal temperament, after 12-et which is able to deal with [[xenharmonic/Harmonic Limit|5-limit]] music in a tolerable manner, and is the fifth (after 12) [[xenharmonic/The Riemann Zeta Function and Tuning#Zeta%20EDO%20lists|zeta integral edo]]. It is less successful with [[xenharmonic/7-limit|7-limit]] (but still better than 12-et), as it eliminates the distinction between a septimal minor third ([[xenharmonic/7_6|7/6]]), and a septimal whole tone ([[xenharmonic/8_7|8/7]]). 19-EDO also has the advantage of being excellent for negri, keemun, godzilla, magic/muggles and triton/liese, and fairly decent for sensi. Keemun and Negri are of particular note for being very simple 7-limit temperaments, with their MOS scales in 19-EDO offering a great abundance of septimal tetrads. The [[xenharmonic/Graham complexity|Graham complexity]] of a 7-limit tetrad is 6 for keemun, 7 for negri, 8 for godzilla, 10 for meantone/flattone, 11 for triton, 12 for magic/muggles and 13 for sensi.

Being a zeta integral tuning, the 13-limit is represented relatively well, and practically [[19edo|19-edo]] can be used //adaptively// on instruments which are allowing you to bend notes up: by different amounts, the 3rd, 5th, 7th and 13th harmonics are all tuned flat. The same cannot be said of 12edo, in which the 5th, 7th and 11th are - not only farther than they are in 19, but fairly sharp already.

In music, &lt;strong&gt;19 equal temperament&lt;/strong&gt;, called 19-TET, 19-&lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/EDO"&gt;EDO&lt;/a&gt;, or 19-ET, is the scale derived by dividing the &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/octave"&gt;octave&lt;/a&gt; into 19 &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/equal"&gt;equal&lt;/a&gt;ly large steps. Each &lt;u&gt;[[#|step]]&lt;/u&gt; represents a frequency ratio of the 19th root of 2, or 63.16 &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/cent"&gt;cents&lt;/a&gt;. It is the 8th &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/prime%20numbers"&gt;prime&lt;/a&gt; edo, following &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/17edo"&gt;17edo&lt;/a&gt; and coming before &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/23edo"&gt;23edo&lt;/a&gt;.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Interest in this tuning system goes back to the sixteenth century, when composer Guillaume Costeley used it in his chanson &lt;a class="wiki_link" href="/Seigneur%20Dieu%20ta%20piti%C3%A9"&gt;Seigneur Dieu ta pitié&lt;/a&gt; of 1558. Costeley understood and desired the circulating aspect of this tuning; in 1577 music theorist Francisco de Salinas in effect proposed it. Salinas discussed &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/1-3%20Syntonic%20Comma%20Meantone"&gt;1/3-comma meantone&lt;/a&gt;, in which the fifth is of size 694.786 cents; the fifth of 19-et is 694.737, which is only a twentieth of a cent flatter. Salinas suggested tuning nineteen tones to the octave to this tuning, which fails to &lt;u&gt;[[#|close]]&lt;/u&gt; by less than a cent, so that his suggestion is effectively 19-et. In the nineteenth century mathematician and music theorist Wesley Woolhouse proposed it as a more practical alternative to meantone tunings he regarded as better, such as &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/50edo"&gt;50 equal temperament&lt;/a&gt; (&lt;a class="wiki_link_ext" href="http://sonic-arts.org/monzo/woolhouse/essay.htm" rel="nofollow"&gt;summary of Woolhouse's essay&lt;/a&gt;).&lt;br /&gt;

  &lt;br /&gt;
  &lt;br /&gt;
The most salient characteristic of 19-et is that, having an almost just minor third and perfect fifths and major thirds about seven cents narrow, it serves as a good tuning for &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/Meantone%20family"&gt;meantone&lt;/a&gt; temperament. It is also a suitable for &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/Regular%20Temperaments#magic"&gt;magic/muggles&lt;/a&gt; temperament, because five of its major thirds are equivalent to one of its &lt;em&gt;twelfths.&lt;/em&gt; For both of these there are more optimal tunings: the fifth of 19-et is flatter than the usual for meantone, and a more accurate approximation is &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/31edo"&gt;31 equal temperament&lt;/a&gt;. Similarly, the generating interval of magic temperament is a major third, and again 19-et's is flatter; &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/41edo"&gt;41 equal temperament&lt;/a&gt; more closely &lt;u&gt;[[#|matches]]&lt;/u&gt; it. It does make for a good tuning for muggles, which in 19et is the same as magic.&lt;br /&gt;

&lt;br /&gt;

However, for all of these 19-et has the practical advantage of requiring fewer pitches, which makes physical realizations of it easier to build. (Many 19-et instruments have been built.) 19-et is in fact the second equal temperament, after 12-et which is able to deal with &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/Harmonic%20Limit"&gt;5-limit&lt;/a&gt; music in a tolerable manner, and is the fifth (after 12) &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/The%20Riemann%20Zeta%20Function%20and%20Tuning#Zeta%20EDO%20lists"&gt;zeta integral edo&lt;/a&gt;. It is less successful with &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/7-limit"&gt;7-limit&lt;/a&gt; (but still better than 12-et), as it eliminates the distinction between a septimal minor third (&lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/7_6"&gt;7/6&lt;/a&gt;), and a septimal whole tone (&lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/8_7"&gt;8/7&lt;/a&gt;). 19-EDO also has the advantage of being excellent for negri, keemun, godzilla, magic/muggles and triton/liese, and fairly decent for sensi. Keemun and Negri are of particular note for being very simple 7-limit temperaments, with their MOS scales in 19-EDO offering a great abundance of septimal tetrads. The &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/Graham%20complexity"&gt;Graham complexity&lt;/a&gt; of a 7-limit tetrad is 6 for keemun, 7 for negri, 8 for godzilla, 10 for meantone/flattone, 11 for triton, 12 for magic/muggles and 13 for sensi. &lt;br /&gt;

Being a zeta integral tuning, the 13-limit is represented relatively well, and practically &lt;a class="wiki_link" href="/19edo"&gt;19-edo&lt;/a&gt; can be used &lt;em&gt;adaptively&lt;/em&gt; on instruments which are allowing you to bend notes up: by different amounts, the 3rd, 5th, 7th and 13th harmonics are all tuned flat. The same cannot be said of 12edo, in which the 5th, 7th and 11th are - not only farther than they are in 19, but fairly sharp already.&lt;br /&gt;
