Original Wikitext content:
<span style="display: block; text-align: right;">[[5平均律|日本語]] </span> [[toc|flat]] ---- =5 Equal Divisions of the Octave: Theory= ==="Equal Pentatonic"=== 5-edo divides the 1200-[[cent]] octave into 5 equal parts, making its smallest interval exactly 240 [[cent|cents]], or the fifth root of two. 5-edo is the 3rd [[prime numbers|prime]] edo, after [[2edo]] and [[3edo]]. Most importantly, 5-edo is the smallest [[edo]] containing xenharmonic intervals! (1edo 2edo 3edo 4edo are all subsets of 12edo.) There is a lot of near-equipentatonic world music, just google "gyil" or "amadinda" or "slendro". ==Listen to the sound of the 5-edo scale== For any musician, there is no substitute for the experience of a particular xenharmonic sound. The user going by the name Hyacinth on Wikipedia and Wikimedia Commons has many xenharmonic MIDI's and has graciously copylefted them! This is his 5-edo scale MIDI: [[@http://commons.wikimedia.org/wiki/File:5-tet_scale_on_C.mid]] ==Intervals in 5-edo== ||~ degrees ||~ size in [[cent|cents]] ||~ Closest diatonic interval name ||~ The "neighborhood" of just intervals || ||= 0 ||= 0 ||= unison / prime || exactly 1/1 || ||= 1 ||= 240 ||= second, third || +8.826¢ from septimal second [[8_7|8/7]] -4.969¢ from diminished third [[144_125|144/125]] -13.076¢ from augmented second 125/108 -26.871¢ from septimal minor third [[7_6|7/6]] || ||= 2 ||= 480 ||= fourth || +9.219¢ from narrow fourth [[21_16|21/16]] -0.686¢ from smaller fourth [[33_25|33/25]] -18.045¢ from just fourth [[4_3|4/3]] || ||= 3 ||= 720 ||= fifth || +18.045¢ from just fifth [[3_2|3/2]] +0.686¢ from bigger fifth [[50_33|50/33]] -9.219¢ from wide fifth [[32_21|32/21]] || ||= 4 ||= 960 ||= sixth, seventh || 26.871¢ from septimal major sixth [[12_7|12/7]] 13.076¢ from diminished seventh 216/125 4.969¢ from augmented sixth [[125_72|125/72]] -8.826¢ from septimal seventh [[7_4|7/4]] || ||= 5 ||= 1200 ||= octave / eighth || exactly 2/1 || [[media type="custom" key="24802268"]] [[file:5ed2-001.svg]] ==Related scales== * By its cardinality, 5-edo is related to other [[pentatonic]] scales, and it is especially close in sound to many Indonesian [[slendro|slendros]]. * Due to the interest around the "fifth" interval size, there are many [[nonoctave]] "stretch sisters" to 5-edo: square root of 4/3, cube root of 3/2, 8th root of 3, etc. * For the same reason there are many "circle sisters": ** Make a chain of five "bigger fifths" (50/33), which makes three octaves 3.227¢ flat. (50/33)^5=7.985099. ==As a temperament== If 5-edo is regarded as a temperament, which is to say as 5-et, then the most salient fact is that 16/15 is tempered out. This means in 5-et the major third and the fourth, and the minor sixth and the fifth, are not distinguished; this is 5-limit [[Trienstonic clan|father temperament]]. Also tempered out is 27/25, if we temper this out in preference to 16/15 we obtain [[Bug family|bug temperament]], which equates 10/9 with 6/5: it is a little more perverse even than father. Because these intervals are so large, this sort of analysis is less significant with 5 than it becomes with larger and more accurate divisions, but it still plays a role. For example, I-IV-V-I is the same as I-III-V-I and involves triads with common intervals because of fourth-thirds equivalence. Despite its lack of accuracy, 5EDO is the second [[The Riemann Zeta Function and Tuning#Zeta%20EDO%20lists|zeta integral edo]], after 2EDO. It also is the smallest equal division representing the [[9-limit]] [[consistent]]ly, giving a distinct value modulo five to 2, 3, 5, 7 and 9. Hence in a way similar to how [[4edo]] can be used, and which is discussed in that article, it can be used to represent [[7-limit]] intervals in terms of their position in a pentad, by giving a triple of integers representing a pentad in the [[The Seven Limit Symmetrical Lattices|lattice]] of tetrads/pentads together with the number of scale steps in 5EDO. However, while [[2edo]] represents the [[3-limit]] consistently, [[3edo]] the [[5-limit]], [[4edo]] the [[7-limit]] and [[5edo]] the [[9-limit]], to represent the [[11-limit]] consistently with a [[patent val]] requires going all the way to [[22edo]]. ==Cycles, Divisions== 5 is a prime number so 5-edo contains no sub-edos. Only simple cycles: Cycle of seconds: 0-1-2-3-4-0 Cycle of fourths: 0-2-4-1-3-0 Cycle of fifths: 0-3-1-4-2-0 Cycle of sevenths: 0-4-3-2-1-0 =5-edo in Musicmaking= ==**Compositions**, improvisations== ** [[http://www.io.com/%7Ehmiller/|Herman Miller]]: //[[http://micro.soonlabel.com/herman_miller/Daybreak.mp3|Daybreak on Slendro Mountain]]// (2000) ** Aaron K.

The 240 cent interval can serve as either a major second or minor third, and the 960 cent interval as either a major sixth or minor seventh. The fourth is about 18 cents flat of a just fourth, making it rather "dirty" but recognizable. The fifth is likewise about 18 cents sharp of a just fifth, dissonant but still easily recognizable. Important chords: * 0+1+3 * 0+2+3 * 0+1+3+4 * 0+2+3+4 ==Melody== Smallest edo which can be used for melodies in a "standard" way. Relatively large step of 240 c can be used as major second for the melody construction. The scale has whole-tone as well as pentatonic character. ==Chord or scale?== Either way, it is hard to wander very far from where you start. However, it has the scale-like feature that there are (barely) enough notes to create melody, in the form of an equal version of pentatonic. ==Commas Tempered== 5-EDO tempers out the following commas.

<!-- ws:start:WikiTextHeadingRule:11:<h2> --><h2 id="toc5"><a name="x5 Equal Divisions of the Octave: Theory-As a temperament"></a><!-- ws:end:WikiTextHeadingRule:11 -->As a temperament</h2>
If 5-edo is regarded as a temperament, which is to say as 5-et, then the most salient fact is that 16/15 is tempered out. This means in 5-et the major third and the fourth, and the minor sixth and the fifth, are not distinguished; this is 5-limit <a class="wiki_link" href="/Trienstonic%20clan">father temperament</a>.<br />
<br />
Also tempered out is 27/25, if we temper this out in preference to 16/15 we obtain <a class="wiki_link" href="/Bug%20family">bug temperament</a>, which equates 10/9 with 6/5: it is a little more perverse even than father. Because these intervals are so large, this sort of analysis is less significant with 5 than it becomes with larger and more accurate divisions, but it still plays a role. For example, I-IV-V-I is the same as I-III-V-I and involves triads with common intervals because of fourth-thirds equivalence.<br />
<br />
Despite its lack of accuracy, 5EDO is the second <a class="wiki_link" href="/The%20Riemann%20Zeta%20Function%20and%20Tuning#Zeta%20EDO%20lists">zeta integral edo</a>, after 2EDO. It also is the smallest equal division representing the <a class="wiki_link" href="/9-limit">9-limit</a> <a class="wiki_link" href="/consistent">consistent</a>ly, giving a distinct value modulo five to 2, 3, 5, 7 and 9. Hence in a way similar to how <a class="wiki_link" href="/4edo">4edo</a> can be used, and which is discussed in that article, it can be used to represent <a class="wiki_link" href="/7-limit">7-limit</a> intervals in terms of their position in a pentad, by giving a triple of integers representing a pentad in the <a class="wiki_link" href="/The%20Seven%20Limit%20Symmetrical%20Lattices">lattice</a> of tetrads/pentads together with the number of scale steps in 5EDO. However, while <a class="wiki_link" href="/2edo">2edo</a> represents the <a class="wiki_link" href="/3-limit">3-limit</a> consistently, <a class="wiki_link" href="/3edo">3edo</a> the <a class="wiki_link" href="/5-limit">5-limit</a>, <a class="wiki_link" href="/4edo">4edo</a> the <a class="wiki_link" href="/7-limit">7-limit</a> and <a class="wiki_link" href="/5edo">5edo</a> the <a class="wiki_link" href="/9-limit">9-limit</a>, to represent the <a class="wiki_link" href="/11-limit">11-limit</a> consistently with a <a class="wiki_link" href="/patent%20val">patent val</a> requires going all the way to <a class="wiki_link" href="/22edo">22edo</a>.<br />

5edo does not have any strong consonance nor dissonance. The 240 cent interval can serve as either a major second or minor third, and the 960 cent interval as either a major sixth or minor seventh. The fourth is about 18 cents flat of a just fourth, making it rather "dirty" but recognizable. The fifth is likewise about 18 cents sharp of a just fifth, dissonant but still easily recognizable.<br />

<!-- ws:start:WikiTextHeadingRule:25:<h2> --><h2 id="toc12"><a name="x5-edo in Musicmaking-Melody"></a><!-- ws:end:WikiTextHeadingRule:25 -->Melody</h2>
Smallest edo which can be used for melodies in a "standard" way. Relatively large step of 240 c can be used as major second for the melody construction. The scale has whole-tone as well as pentatonic character.<br />
<br />
<!-- ws:start:WikiTextHeadingRule:27:<h2> --><h2 id="toc13"><a name="x5-edo in Musicmaking-Chord or scale?"></a><!-- ws:end:WikiTextHeadingRule:27 -->Chord or scale?</h2>
Either way, it is hard to wander very far from where you start. However, it has the scale-like feature that there are (barely) enough notes to create melody, in the form of an equal version of pentatonic.<br />
