'''4L 3s''', named '''smitonic''', is a moment-of-symmetry scale characterized by having 4 large steps and 3 small steps distributed as evenly as possible within the octave. Generators that produce this scale range from (bright-gen-range), or from (dark-gen-range). | |||
4L 3s can be seen as a [[Warped diatonic|warped diatonic scale]], where one large step of diatonic ([[5L 2s]]) is replaced with a small step. | |||
== Scale characteristics == | |||
''This article assumes TAMNAMS naming conventions for the following: step ratios, intervals, scale degrees, modes, step patterns. For more information, see the respective links.'' | |||
== Name == | ===Name === | ||
'' | [[TAMNAMS]] suggests the temperament-agnostic name '''smitonic''' ''smy-TON-ik'' /smaɪˈtɒnɪk/ for this scale. The name is derived from 'sharp minor third', since the central range for the dark generator (320¢ to 333.3¢) is significantly sharp of [[6/5]] (just minor 3rd, 315.6¢). | ||

=== Modes and scale degrees === | |||
Alexandru Ianu ([[User:Ayceman|Ayceman]])<ref>Description of ''Sylvian Moon Dance'' mentioning the naming proposal https://musescore.com/user/36772625/scores/6700443 – The theme relates to the mystical nature of the Tribunal and TES lore, which fits smitonic.</ref> has proposed the following mode names relating to the Almsivi in Morrowind (TES): | |||
{{MOS mode degrees|Mode Names=Nerevarine; Vivecan; Lorkhanic; Sothic; Kagrenacan; Almalexian; Dagothic|Scale Signature=4L 3s}} | |||
==Theory== | |||
===Low harmonic entropy scales=== | |||
There are two notable harmonic entropy minima: | |||
*[[Kleismic family|Kleismic temperament]], in which the generator is 6/5 and 6 of them make a 3/1. | |||
*[[myna|Myna temperament]], in which the generator is also 6/5 but 10 of them make a 6/1, resulting in the intervals 4/3 and 3/2 being absent. | |||
===Temperament interpretations=== | |||
:''Main article: [[4L 3s/Temperaments]]'' | |||
4L 3s has the following temperament interpretations: | |||
*[[Sixix]], with generators around 338.6¢. | |||
*[[Orgone]], with generators around 323.4¢. | |||
*[[Kleismic]], with generators around 317¢. | |||
Other temperaments, such as [[amity]] and [[myna]], require more than 7 pitches to contain the concordant chords optimized by these temperaments. If restricted to a rank-2 approach, a [[MODMOS]] or a larger MOS gamut is necessary to access these pitches. | |||
== Tuning ranges == | |||
===Simple tunings=== | |||
The basic tuning for 4L 3s has a large and small step size of 2 and 1 respectively, which is supported by 11edo. Other small edos include [[15edo]] and [[18edo]]. | |||
===Parasoft tunings=== | |||
Parasoft smitonic tunings (4:3 to 3:2) can be considered "meantone smitonic" since it has the following features of [[meantone]] diatonic tunings: | |||
*The major 1-mosstep, or large step, is around [[10/9]] to [[9/8]], thus making it a "meantone". | |||
* The augmented 2-mosstep is around the size of a meantone-sized major 3rd and can be used as a stand-in for such. | |||
These tunings have a major 4-mosstep and minor 4-mosstep that are about equally off a just 3/2 (702¢), and they have otherwise fairly convincing versions of both diatonic structure and tertian harmony, provided you frequently modify using the comma-like chromas. For this reason, parasoft might be the most accessible smitonic tuning range. | |||
Edos include [[18edo]], [[25edo]], and [[43edo]]. Some key considerations include: | |||
*18edo can be used to make the large and small steps more distinct, or can be considered a distorted 19edo diatonic. | |||
**18edo has a major 1-mosstep that is close to 9/8 (203¢). | |||
**18edo's major and minor 4-mossteps are both equally off from 12edo's diatonic perfect 5th (700¢) by 33.3¢. | |||
** 18edo is also more suited for conventionally jazz styles due to its 6-fold symmetry. | |||
* The augmented 2-mosstep of 25edo is very close to 5/4 (386¢). | |||
*The various interval flavors separated by a chroma shows that parasoft smitonic is a useful [[cluster MOS]]. However, many of these intervals lack simple JI interpretations. | |||
===Hyposoft tunings=== | |||
Hyposoft smitonic tunings (3:2 to 2:1) are characterized by generators that are a supraminor 3rd, between 327¢ and 333¢. By analogy of parasoft tunings being called "meantone smitonic", these tunings can be considered "[[Gentle region|neogothic]] smitonic" or "[[archy]] smitonic". | |||
Edos include [[11edo]] (not shown), [[18edo]], and [[29edo]]. | |||
===Hypohard tunings=== | |||
Hypohard smitonic tunings (2:1 to 3:1) have generators between 320¢ and 327¢. The major 1-mosstep, or large step, tends to approximate [[8/7]] (231¢) and the major 3-mosstep tends to approximate [[11/8]] (551¢). [[26edo]] approximates these two intervals very well. These JI approximations are associated with [[orgone]] temperament. | |||
== | Other hypohard edos include [[11edo]] (not shown), [[15edo]] and [[37edo]]. | ||
===Parahard tunings=== | |||
Parahard smitonic tunings (3:1 to 4:1) have generators between 315.9¢ and 320¢, putting it close to a pure 6/5 (316¢). Stacking six generators and octave-reducing approximates 3/2 (702¢), a diatonic perfect 5th, represented by the diminished 5-mosstep. | |||
This range contains very accurate edos such as [[53edo]] and [[72edo]], and has very accurate approximations to many [[low-overtone JI]] intervals, namely basic [[5-limit]] ratios and some ratios involving 13. However, 4L 3s only has one interval of 3/2, so it's suggested to use a larger MOS, such as [[4L 7s]], to achieve 5-limit harmony. | |||
These JI approximations are associated with [[kleismic]] temperament, though the 2.3.5.13 extension described here is called [[Chromatic pairs#Cata|cata]]. | |||
Parahard edos smaller than 53edo include [[15edo]] (not shown), [[19edo]], and [[34edo]]. | |||
