The '''slendro clan''' tempers out the slendro diesis, [[49/48]], a triprime comma with factors of 2, 3 and 7.  
{{Technical data page}}
The '''semaphoresmic clan''' (or '''semaphore family''') of [[regular temperament|temperaments]] [[tempering out|tempers out]] the large septimal diesis, or semaphoresma, [[49/48]], a triprime comma with factors of 2, 3 and 7.
 
This article focuses on rank-2 temperaments. See [[Semaphoresmic family]] for the rank-3 temperament resulting from tempering out 49/48 alone in the full 7-limit.

Semaphore tempers out 49/48, and splits a [[3/1|perfect twelfth]] into two halfs of [[7/4]][[~]][[12/7]], and a [[4/3|perfect fourth]] into two halfs of [[7/6]]~[[8/7]], hence the name ''semaphore'', which sounds like ''semifourth''; its [[ploidacot]] is alpha-dicot. [[19edo]] and [[24edo]] are among the possible edo tunings.

=== Overview to extensions ===
The second comma of the comma list defines which 7-limit family member we are looking at.  
The second comma of the comma list defines which 7-limit family member we are looking at:
* Beep adds [[21/20]], for a tuning flat of 9edo;
* Superpelog adds [[135/128]], for a tuning between 9edo and 14c-edo;
* Godzilla adds [[81/80]], for a tuning between 14c-edo and 24edo;
* Helayo adds [[3645/3584]], for a tuning between 14edo and 24c-edo;
* Immunity adds [[2240/2187]], for a tuning sharp of 29edo;
* Baba adds [[16/15]], for a niche exotemperament well tuned around 11b-edo.  


Godzilla adds [[81/80]]. Immunity adds [[2240/2187]]. Superpelog adds [[135/128]]. Beep adds [[21/20]]. Baba adds [[16/15]]. These all use the same nominal generator as semaphore, though some of them are of very low accuracy.  
These all use the same nominal generator as semaphore, though some of them are of very low accuracy.  


Decimal adds [[25/24]], splitting the octave in two. Negri adds [[225/224]], splitting the hemifourth in two. Triforce adds [[128/125]], splitting the octave in three. Keemun adds [[126/125]], splitting the hemitwelfth in three. Nautilus adds [[250/243]], splitting the hemifourth in three. Nuke is like nautilus, but adds 3584/3375 instead. Blacksmith adds [[28/27]], splitting the octave in five. Spell adds [[3125/3072]], splitting the hemitwelfth in five. Hemiripple adds 6561/6250, splitting the hemifourth in five. Finally, mabila adds 28672/28125 and splits an interval of two octaves plus a hemifourth in five.  
Decimal adds [[25/24]]. Anguirus adds [[2048/2025]]. Those split the octave in two. Negri adds [[225/224]], splitting the hemifourth in two. Triforce adds [[128/125]], splitting the octave in three. Keemun adds [[126/125]], splitting the hemitwelfth in three. Nautilus adds [[250/243]], splitting the hemifourth in three. Nuke is like nautilus, but adds 3584/3375 instead. Hemidim adds [[648/625]] with a 1/4-octave period. Rhinoceros adds [[4375/4374]], splitting the hemifourth in four. Spell adds [[3125/3072]], splitting the hemitwelfth in five. Hemiripple adds 6561/6250, splitting the hemifourth in five. Semabila adds 28672/28125 and splits an interval of two octaves plus a hemifourth in five. Finally, blackwood adds [[28/27]], reducing intervals of 3 and 7 to the same chain of 1/5-octave periods.

Godzilla tempers out [[81/80]], equating 9/8 and 10/9, so it finds the prime 5 at a stack of four fifths, as does any temperament in the [[meantone family]]. [[19edo]] is close to being the optimal generator tuning; hence it can be more or less equated with taking 4\19 as a generator. [[Mos scale]]s are of 5, 9, or 14 notes.
Godzilla tempers out [[81/80]], equating [[9/8]] and [[10/9]], so it finds the prime 5 at a stack of four fifths, as does any temperament in the [[meantone family]]. Like many entries of this clan, godzilla can be extended naturally to the 2.3.5.7.13 subgroup by identifying the hemifourth as ~15/13, tempering out [[91/90]] and [[105/104]]. [[19edo]] is close to being the optimal generator tuning; hence it can be more or less equated with taking 4\19 as a generator. [[Mos scale]]s are of 5, 9, or 14 notes.

Helayo tempers out 3645/3584 and may be thought of as the opposite of godzilla with respect to 19edo. Like godzilla, 19edo's generator is close to the optimum.

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The semaphoresmic clan (or semaphore family) of temperaments tempers out the large septimal diesis, or semaphoresma, 49/48, a triprime comma with factors of 2, 3 and 7.

This article focuses on rank-2 temperaments. See Semaphoresmic family for the rank-3 temperament resulting from tempering out 49/48 alone in the full 7-limit.

Semaphore

Main article: Semaphore and godzilla

Semaphore tempers out 49/48, and splits a perfect twelfth into two halfs of 7/4~12/7, and a perfect fourth into two halfs of 7/6~8/7, hence the name semaphore, which sounds like semifourth; its ploidacot is alpha-dicot. 19edo and 24edo are among the possible edo tunings.

Subgroup: 2.3.7

Comma list: 49/48

Subgroup-val mapping: [⟨1 0 2], ⟨0 2 1]]

Gencom mapping: [⟨1 0 0 2], ⟨0 2 0 1]]

  • CWE: ~2 = 1200.0000 ¢, ~7/4 = 950.6890 ¢

Overview to extensions

The second comma of the comma list defines which 7-limit family member we are looking at:

  • Beep adds 21/20, for a tuning flat of 9edo;
  • Superpelog adds 135/128, for a tuning between 9edo and 14c-edo;
  • Godzilla adds 81/80, for a tuning between 14c-edo and 24edo;
  • Helayo adds 3645/3584, for a tuning between 14edo and 24c-edo;
  • Immunity adds 2240/2187, for a tuning sharp of 29edo;
  • Baba adds 16/15, for a niche exotemperament well tuned around 11b-edo.

These all use the same nominal generator as semaphore, though some of them are of very low accuracy.

Decimal adds 25/24. Anguirus adds 2048/2025. Those split the octave in two. Negri adds 225/224, splitting the hemifourth in two. Triforce adds 128/125, splitting the octave in three. Keemun adds 126/125, splitting the hemitwelfth in three. Nautilus adds 250/243, splitting the hemifourth in three. Nuke is like nautilus, but adds 3584/3375 instead. Hemidim adds 648/625 with a 1/4-octave period. Rhinoceros adds 4375/4374, splitting the hemifourth in four. Spell adds 3125/3072, splitting the hemitwelfth in five. Hemiripple adds 6561/6250, splitting the hemifourth in five. Semabila adds 28672/28125 and splits an interval of two octaves plus a hemifourth in five. Finally, blackwood adds 28/27, reducing intervals of 3 and 7 to the same chain of 1/5-octave periods.

Considered below are godzilla, helayo, superpelog, baba, negri, and nuke.

Semaerophore

Named by CompactStar in 2023, this extension tempers out 729/704. It is the no-5 restriction of undecimal godzilla.

Subgroup: 2.3.7.11

Comma list: 49/48, 729/704

Subgroup-val mapping: [⟨1 0 2 -6], ⟨0 2 1 12]]

Optimal tunings:

  • WE: ~2 = 1204.9027 ¢, ~7/4 = 948.7772 ¢
  • CWE: ~2 = 1200.0000 ¢, ~7/4 = 945.4959 ¢

Optimal ET sequence: 14, 33d, 47de

Badness (Sintel): 1.27

2.3.7.11.19 subgroup

Subgroup: 2.3.7.11.19

Comma list: 49/48, 77/76, 729/704

Subgroup-val mapping: [⟨1 0 2 -6 -6], ⟨0 2 1 12 13]]

Optimal tunings:

  • WE: ~2 = 1204.9645 ¢, ~7/4 = 948.5749 ¢
  • CWE: ~2 = 1200.0000 ¢, ~7/4 = 945.2236 ¢

Optimal ET sequence: 14, 33d, 47deh

Badness (Sintel): 1.08

Godzilla

Main article: Semaphore and godzilla

Godzilla tempers out 81/80, equating 9/8 and 10/9, so it finds the prime 5 at a stack of four fifths, as does any temperament in the meantone family. Like many entries of this clan, godzilla can be extended naturally to the 2.3.5.7.13 subgroup by identifying the hemifourth as ~15/13, tempering out 91/90 and 105/104. 19edo is close to being the optimal generator tuning; hence it can be more or less equated with taking 4\19 as a generator. Mos scales are of 5, 9, or 14 notes.

Helayo

For the 5-limit version of this temperament see Syntonic–kleismic equivalence continuum #Hogzilla.

Helayo tempers out 3645/3584 and may be thought of as the opposite of godzilla with respect to 19edo. Like godzilla, 19edo's generator is close to the optimum.

Negri

Main article: Negri
For the 5-limit version, see Syntonic–kleismic equivalence continuum #Negri (5-limit).

Negri tempers out the negri comma in the 5-limit, 49/48 and 225/224 in the 7-limit. It may be described as 9 & 10; its ploidacot is omega-tetracot. It can be extended naturally to the 2.3.5.7.13 subgroup by adding 91/90 and/or 105/104 to the comma list; this will be discussed below under the title of negra.
