The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.
Original Wikitext content:
=<span style="background-color: #000000; color: #009927; font-size: 109%;">23 tone equal temperament</span>= 23et, or 23-EDO, is a tuning system which divides the [[octave]] into 23 equal parts of approximately 52.173913 cents. It has good approximations for [[5_3|5/3]], [[11_7|11/7]], 13 and 17, allowing it to represent the 2.5/3.11/7.13.17 [[just intonation subgroup]]. If to this subgroup is added the commas of [[17-limit]] [[46edo|46et]], the larger 17-limit [[k*N subgroups|2*23 subgroup]] 2.9.15.21.33.13.17 is obtained. This is the largest subgroup on which 23 has the same tuning and commas as does 17-limit 46, and may be regarded as a basis for analyzing the harmony of 23-EDO so far as approximations to just intervals goes. 23-EDO was proposed by ethnomusicologist [[http://en.wikipedia.org/wiki/Erich_von_Hornbostel|Erich von Hornbostel]] as the result of continuing a circle of "blown" fifths of ~678-cent fifths that (he argued) resulted from "overblowing" a bamboo pipe. 23-EDO is also significant in that it is the largest EDO that fails to approximate the 3rd, 5th, and 7th harmonics within 20 cents, which makes it well-suited for musicians seeking to explore unusual harmonic territory. Oddly, despite the fact that it fails to approximate these harmonics, it approximates the intervals between them (5/3, 7/3, and 7/5) very well. The lowest harmonics well-approximated by 23-EDO are 13, 17, 21, and 23. Like 9-EDO, 16-EDO, and 25-EDO, one way to treat 23-EDO is as a Pelogic temperament, tempering out the "comma" of 135/128 and equating three sharp 4/3's with 5/1 (related to the Armodue system). This means mapping 3/2 to 13 degrees of 23, and results in a 7-note "anti-diatonic" scale of 3 3 4 3 3 3 4 (in steps of 23-EDO), which extends to 9 notes (3 3 3 1 3 3 3 3 1). However, one can also map 3/2 to 14 degrees of 23-EDO without significantly increasing the error, taking us to a 7-limit temperament where two 3/2's equals 7/3, meaning 28/27 is tempered out, and six 4/3's octave-reduced equals 5/4, meaning 4096/3645 is tempered out. Both of these are very large commas, so this is not at all an accurate temperament, but it is related to 13-EDO and 18-EDO and produces MOS scales of 5 and 8 notes: 5 5 4 5 4 (the "anti-pentatonic") and 4 1 4 1 4 4 1 4 (the "quarter-tone" version of the Blackwood/[[http://en.wikipedia.org/wiki/Paul_Rapoport_%28music_critic%29|Rapoport]]/Wilson 13-EDO "subminor" scale). Alternatively we can treat this temperament as a 2.9.21 subgroup, and instead of calling 9 degrees of 23-EDO a "4/3", we can call it 21/16. Here three 21/16's gets us to 9/4, meaning 1029/1024 is tempered out. This allows us to treat a triad of 0-4-9 degrees of 23-EDO as an approximation to 16:18:21, and 0-5-9 as 1/(16:18:21); both of these triads are abundant in the 8-note MOS scale. I would argue that the most significant modes of 23 edo are those of the 2 2 2 3 2 2 3 2 2 3 scale ([[3L 7s|3L 7s fair mosh]]); This is derived from extending the ~1/3 comma tempered 13th harmonic, two of which add up to the h21 and three add up to the h17 almost perfectly (I discovered the temperament before I even realised 23 tone fits) The chord 8:13:21:34 is a fragment of the fibonacci sequence, and 16:21:26 is harmonically symmetrical (The chord 26:29:32 is also symmetric, but only 20 and 43 edo approximate the h29 as well) 13:17:21 is symmetrical, and 17:21:26:32 has an interesting linear widening pattern, but more importantly, the h13 and h17 are both dual primes like 3&5 and 7&11 Thus I have named these 10 modes according to the Sephiroth as follows: 2 2 2 3 2 2 3 2 2 3 - Mode Keter 2 2 3 2 2 3 2 2 3 2 - Chesed 2 3 2 2 3 2 2 3 2 2 - Netzach 3 2 2 3 2 2 3 2 2 2 - Malkuth 2 2 3 2 2 3 2 2 2 3 - Binah 2 3 2 2 3 2 2 2 3 2 - Tiferet 3 2 2 3 2 2 2 3 2 2 - Yesod 2 2 3 2 2 2 3 2 2 3 - Chokmah 2 3 2 2 2 3 2 2 3 2 - Gevurah 3 2 2 2 3 2 2 3 2 2 - Keter -- Kosmorsky =Music= [[http://home.vicnet.net.au/%7Eepoetry/family.mp3|The Family Supper]] by [[Warren Burt]] [[http://www.youtube.com/watch?v=Hqst8MaRiYM|Icositriphonic Heptatonic MOS]] by [[Igliashon Jones]] [[http://clones.soonlabel.com/public/micro/gene_ward_smith/Others/Igs/City%20Of%20The%20Asleep%20-%20His%20Wandering%20Kinship%20with%20Ashes.mp3|His Wandering Kinship with Ashes]] by Iglashion Jones [[http://www.nonoctave.com/tunes/CosmicChamber.mp3|Cosmic Chamber]] by [[X.

This is the largest subgroup on which 23 has the same tuning and commas as does 17-limit 46, and may be regarded as a basis for analyzing the harmony of 23-EDO so far as approximations to just intervals goes.<br /> <br /> 23-EDO was proposed by ethnomusicologist <a class="wiki_link_ext" href="http://en.wikipedia.org/wiki/Erich_von_Hornbostel" rel="nofollow">Erich von Hornbostel</a> as the result of continuing a circle of "blown" fifths of ~678-cent fifths that (he argued) resulted from "overblowing" a bamboo pipe.<br /> <br /> 23-EDO is also significant in that it is the largest EDO that fails to approximate the 3rd, 5th, and 7th harmonics within 20 cents, which makes it well-suited for musicians seeking to explore unusual harmonic territory. Oddly, despite the fact that it fails to approximate these harmonics, it approximates the intervals between them (5/3, 7/3, and 7/5) very well. The lowest harmonics well-approximated by 23-EDO are 13, 17, 21, and 23.<br /> <br /> Like 9-EDO, 16-EDO, and 25-EDO, one way to treat 23-EDO is as a Pelogic temperament, tempering out the "comma" of 135/128 and equating three sharp 4/3's with 5/1 (related to the Armodue system). This means mapping 3/2 to 13 degrees of 23, and results in a 7-note "anti-diatonic" scale of 3 3 4 3 3 3 4 (in steps of 23-EDO), which extends to 9 notes (3 3 3 1 3 3 3 3 1).<br /> <br /> However, one can also map 3/2 to 14 degrees of 23-EDO without significantly increasing the error, taking us to a 7-limit temperament where two 3/2's equals 7/3, meaning 28/27 is tempered out, and six 4/3's octave-reduced equals 5/4, meaning 4096/3645 is tempered out. Both of these are very large commas, so this is not at all an accurate temperament, but it is related to 13-EDO and 18-EDO and produces MOS scales of 5 and 8 notes: 5 5 4 5 4 (the "anti-pentatonic") and 4 1 4 1 4 4 1 4 (the "quarter-tone" version of the Blackwood/<a class="wiki_link_ext" href="http://en.wikipedia.org/wiki/Paul_Rapoport_%28music_critic%29" rel="nofollow">Rapoport</a>/Wilson 13-EDO "subminor" scale). Alternatively we can treat this temperament as a 2.9.21 subgroup, and instead of calling 9 degrees of 23-EDO a "4/3", we can call it 21/16. Here three 21/16's gets us to 9/4, meaning 1029/1024 is tempered out. This allows us to treat a triad of 0-4-9 degrees of 23-EDO as an approximation to 16:18:21, and 0-5-9 as 1/(16:18:21); both of these triads are abundant in the 8-note MOS scale.<br /> <br /> I would argue that the most significant modes of 23 edo are those of the 2 2 2 3 2 2 3 2 2 3 scale (<a class="wiki_link" href="/3L%207s">3L 7s fair mosh</a>);<br /> This is derived from extending the ~1/3 comma tempered 13th harmonic, two of which add up to the h21<br /> and three add up to the h17 almost perfectly (I discovered the temperament before I even realised 23 tone fits)<br /> The chord 8:13:21:34 is a fragment of the fibonacci sequence, and 16:21:26 is harmonically symmetrical<br /> (The chord 26:29:32 is also symmetric, but only 20 and 43 edo approximate the h29 as well)<br /> 13:17:21 is symmetrical, and 17:21:26:32 has an interesting linear widening pattern, but more importantly,<br /> the h13 and h17 are both dual primes like 3&5 and 7&11<br /> <br /> Thus I have named these 10 modes according to the Sephiroth as follows:<br /> 2 2 2 3 2 2 3 2 2 3 - Mode Keter<br /> 2 2 3 2 2 3 2 2 3 2 - Chesed<br /> 2 3 2 2 3 2 2 3 2 2 - Netzach<br /> 3 2 2 3 2 2 3 2 2 2 - Malkuth<br /> 2 2 3 2 2 3 2 2 2 3 - Binah<br /> 2 3 2 2 3 2 2 2 3 2 - Tiferet<br /> 3 2 2 3 2 2 2 3 2 2 - Yesod<br /> 2 2 3 2 2 2 3 2 2 3 - Chokmah<br /> 2 3 2 2 2 3 2 2 3 2 - Gevurah<br /> 3 2 2 2 3 2 2 3 2 2 - Keter<br /> <br /> -- Kosmorsky<br /> <br /> <!-- ws:start:WikiTextHeadingRule:2:<h1> --><h1 id="toc1"><a name="Music"></a><!-- ws:end:WikiTextHeadingRule:2 -->Music</h1> <a class="wiki_link_ext" href="http://home.vicnet.net.au/%7Eepoetry/family.mp3" rel="nofollow">The Family Supper</a> by <a class="wiki_link" href="/Warren%20Burt">Warren Burt</a><br /> <a class="wiki_link_ext" href="http://www.youtube.com/watch?v=Hqst8MaRiYM" rel="nofollow">Icositriphonic Heptatonic MOS</a> by <a class="wiki_link" href="/Igliashon%20Jones">Igliashon Jones</a><br /> <a class="wiki_link_ext" href="http://clones.soonlabel.com/public/micro/gene_ward_smith/Others/Igs/City%20Of%20The%20Asleep%20-%20His%20Wandering%20Kinship%20with%20Ashes.mp3" rel="nofollow">His Wandering Kinship with Ashes</a> by Iglashion Jones<br /> <a class="wiki_link_ext" href="http://www.nonoctave.com/tunes/CosmicChamber.mp3" rel="nofollow">Cosmic Chamber</a> by <a class="wiki_link" href="/X.%20J.%20Scott">X.
