'''3L 5s''' or '''sensoid''' (named after the regular temperament [[sensi]]) refers to the structure of octave-equivalent [[MOS]] scales with generators ranging from 1\3 (one degrees of [[3edo]] = 400¢) to 3\8 (three degrees of [[8edo]] = 450¢). In the case of 8edo, L and s are the same size; in the case of 3edo, s becomes so small it disappears (and all that remains are the three equal L's). The pattern is also named ''antioneirotonic'' because it is the [[oneirotonic]] (5L 3s) MOS pattern with large and small steps switched.<!--
== Name ==
[[TAMNAMS]] suggests the temperament-agnostic name '''checkertonic''' for this scale.


There are two significant harmonic entropy minima with this MOS pattern. [[Sensipent_family|Sensi]], in which the generator is 9/7, two of them make 5/3, and seven of them make 6/1, is the proper one. [[Meantone_family#Squares|Squares]], in which the generator is also 9/7, but two of them make 18/11 and five of them make 8/3, is improper.-->

== Notation ==
{{TAMNAMS use}}
The notation used in this article is JKLMNOPQJ = sLssLsLs (Anti-Ultharian), #/@ = up/down by chroma, N = C4 = 261.6255653 Hz.

=== Parasoft ===
{{MOS intervals}}
Parasoft sensoid is the narrow region between 7\19 (442.1¢) and 10\27 (444.4¢). In the parasoft sensi MOS, root-mos5th-mos8th chords usually approximate 5:7:9 and 7:10:13 chords (shown in the Anti-Dylathian mode QJKLMNOPQ = ssLssLsL):
* Q M P = ssLs sLs L = 5:7:9
* J N Q = sLss LsL s = the odd one out
* K O J = LssL sLs s = 7:10:13
* L P K = ssLs Lss L = 5:7:9
* M Q L = sLsL ssL s = 7:10:13
* N J M = LsLs sLs s = 7:10:13
* O K N = sLss Lss L = 5:7:9
* P L O = LssL ssL s = 7:10:13


Other otonal chords approximated in the parasoft sensoid MOS include:

* root - min. sen3rd - dim. sen6th ≈ 6:7:9
* root - perf. sen4th - dim. sen6th ≈ 10:13:15 (ultramajor triad)
* root - perf. sen4th - maj. sen7th ≈ 7:9:13
* root - perf. sen4th - maj. sen5th - maj. sen7th ≈ 7:9:10:13
* root - perf. sen4th - min. sen5th - min. sen7th ≈ 10:13:14:18
* root - min. sen7th - min. sen3rd (+ octave) ≈ 3:5:7
* root - min. sen7th - min. sen2nd (+ octave) ≈ 6:10:13
* root - dim. sen6th - min. sen7th ≈ 6:9:10
* root - dim. sen6th - min. sen2nd (+octave) ≈ 6:9:13


<!-- Tunings in this region have a regular temperament interpretation called [[Sensi]].-->
==== Proposed mode names ====
 
The modes of checkertonic can be named after its sister mos [[5L 3s]] (oneirotonic). {{u|R-4981}} has also proposed names based on {{w|grand chess}} pieces.

== Notation ==
The [[TAMNAMS]] system is used in this article to refer to {{PAGENAME}} step size ratios and step ratio ranges.
The notation used in this article is JKLMNOPQJ = sLssLsLs (Anti-Ultharian), &amp;/@ = up/down by chroma.
== Theory ==
In contrast to oneirotonic ([[5L&nbsp;3s]]), which often require the usage of completely new chords to have consonant-sounding music, some checkertonic scales contain approximations to a perfect fifth ([[3/2]], usually as a dim. chk6th or maj. chk5th), and thus can be used for traditional root-3rd-P5 harmony.
=== Low harmonic entropy scales ===
There are two significant harmonic entropy minima with this MOS pattern:
* [[Sensipent family|Sensi]], in which the generator is a 9/7, two of them make a 5/3, and seven of them make a 3/2, which is proper.
* [[Meantone family #Squares|Squares]], in which the generator is also a 9/7, but two of them make an 18/11 and four of them make a 4/3, which is improper.
== Tuning ranges ==
=== Simple tunings ===
{{MOS tunings}}
=== Parasoft tunings ===
Parasoft tunings (step ratios 4:3 to 3:2) are associated with [[sensi]] tempermament.
