'''130edo''' divides the octave into 130 parts of size 9.231 cents each.
{{Infobox ET}}
{{ED intro}}


130edo is the tenth [[The_Riemann_Zeta_Function_and_Tuning #Zeta EDO lists|zeta integral edo]] but not a gap edo. It can be used to tune a variety of temperaments, including [[hemiwürschmidt]], [[sesquiquartififths]], [[harry]] and [[hemischismic]]. It also can be used to tune the rank-three temperament [[Breed_family#Jove, aka Wonder|jove]], tempering out [[243/242]] and [[441/440]], plus [[364/363]] for the 13-limit and [[595/594]] for the 17-limit. It gives the [[optimal patent val]] for 11-limit [[Würschmidt_family #Hemiwürschmidt|hemiwürschmidt]] and [[Schismatic_family #Sesquiquartififths|sesquart]] and 13-limit [[Breedsmic_temperaments #Harry|harry]] temperaments.
== Theory ==
130edo is [[distinctly consistent]] to the [[15-odd-limit]]. It is also almost consistent in the no-29 [[31-odd-limit]], missing [[19/11]] (50.5%), [[25/19]] (52.9%), [[17/11]] (64,4%), [[25/17]] (66.8%), and [[octave complement]]s. It is a [[zeta peak edo]], a [[zeta peak integer edo]], and a [[zeta integral edo]] but not a [[zeta gap edo]].  


7-limit commas: 2401/2400, 3136/3125, 19683/19600
As an equal temperament, it [[tempering out|tempers out]] [[2401/2400]], [[3136/3125]], [[6144/6125]], and [[19683/19600]] in the [[7-limit]]; [[243/242]], [[441/440]], [[540/539]], and [[4000/3993]] in the [[11-limit]]; and [[351/350]], [[364/363]], [[676/675]], [[729/728]], [[1001/1000]], [[1575/1573]], [[1716/1715]], [[2080/2079]], [[4096/4095]], and [[4225/4224]] in the [[13-limit]]. It can be used to tune a variety of temperaments, including [[hemiwürschmidt]], [[sesquiquartififths]], [[harry]] and [[hemischis]]. It also can be used to tune the [[rank-3 temperament]] [[jove]], tempering out 243/242 and 441/440, plus 364/363 for the 13-limit and [[595/594]] for the 17-limit. It gives the [[optimal patent val]] for 11-limit [[hemiwürschmidt]] and [[sesquart]] and 13-limit [[harry]].


11-limit commas: 441/440, 540/539, 3136/3125, 4000/3993
=== Prime harmonics ===
{{Harmonics in equal|130|columns=11}}
{{Harmonics in equal|130|columns=11|start=12|collapsed=true|title=Approximation of prime harmonics in 130edo (continued)}}


13-limit commas: 3136/3125, 243/242, 441/440, 351/350, 364/363
=== Subsets and supersets ===
Since 130 factors into primes as {{nowrap| 2 × 5 × 13 }}, 130edo has subset edos {{EDOs| 2, 5, 10, 13, 26, and 65 }}.


17-limit commas: 221/220, 364/363, 442/441, 595/594, 1275/1274, 4913/4875
[[260edo]], which divides the edostep in two, provides a strong correction for the 29th harmonic.

== Notation ==
=== Ups and downs notation ===
130edo can be notated using [[Kite's ups and downs notation|ups and downs]] and quarter-tone accidentals:
{{Ups and downs sharpness|130|true}}
=== Sagittal notation ===
130edo can be notated in [[Sagittal notation|Sagittal]] using the [[Sagittal notation#Spartan single-shaft|Spartan extension]], with the apotome equal to 12 edosteps and the limma to 10 edosteps. Since the the [[243/242|rastma]] is tempered out, a SZ half-sharp and a half-flat may be used instead of pakai/pakao. Here is a simplified table:

Because it uses the entire Spartan extension, it allows no accidental enharmonic respellings.

Prime factorization 2 × 5 × 13

130 equal divisions of the octave (abbreviated 130edo or 130ed2), also called 130-tone equal temperament (130tet) or 130 equal temperament (130et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 130 equal parts of about 9.23 ¢ each. Each step represents a frequency ratio of 21/130, or the 130th root of 2.

Theory

130edo is distinctly consistent to the 15-odd-limit. It is also almost consistent in the no-29 31-odd-limit, missing 19/11 (50.5%), 25/19 (52.9%), 17/11 (64,4%), 25/17 (66.8%), and octave complements. It is a zeta peak edo, a zeta peak integer edo, and a zeta integral edo but not a zeta gap edo.

As an equal temperament, it tempers out 2401/2400, 3136/3125, 6144/6125, and 19683/19600 in the 7-limit; 243/242, 441/440, 540/539, and 4000/3993 in the 11-limit; and 351/350, 364/363, 676/675, 729/728, 1001/1000, 1575/1573, 1716/1715, 2080/2079, 4096/4095, and 4225/4224 in the 13-limit. It can be used to tune a variety of temperaments, including hemiwürschmidt, sesquiquartififths, harry and hemischis. It also can be used to tune the rank-3 temperament jove, tempering out 243/242 and 441/440, plus 364/363 for the 13-limit and 595/594 for the 17-limit. It gives the optimal patent val for 11-limit hemiwürschmidt and sesquart and 13-limit harry.

Subsets and supersets

Since 130 factors into primes as 2 × 5 × 13, 130edo has subset edos 2, 5, 10, 13, 26, and 65.

260edo, which divides the edostep in two, provides a strong correction for the 29th harmonic.

Notation

Ups and downs notation

130edo can be notated using ups and downs and quarter-tone accidentals:

Sagittal notation

130edo can be notated in Sagittal using the Spartan extension, with the apotome equal to 12 edosteps and the limma to 10 edosteps. Since the the rastma is tempered out, a SZ half-sharp and a half-flat may be used instead of pakai/pakao. Here is a simplified table:

Steps 0 1 2 3 4 5 6 7 8 9 10 11 12
Symbol Evo+SZ
Evo
Revo

Because it uses the entire Spartan extension, it allows no accidental enharmonic respellings.
