[[TAMNAMS]] suggests the temperament-agnostic name '''checkertonic''' for this scale.

== Scale properties ==
:''This article assumes [[TAMNAMS]] for naming step ratios, intevrvals, and scale degrees.''
{{TAMNAMS use}}


Names for this scale's intervals (mossteps) and scale degrees (mosdegrees) are based on the number of large and small steps from the root, starting at 0 (0-mosstep and 0-mosdegree) for the unison, per TAMNAMS. Ordinal names, such as mos-1st for the unison, are discouraged for non-diatonic MOS scales.

The notation used in this article is JKLMNOPQJ = sLssLsLs (Anti-Ultharian), &/@ = up/down by chroma.
=== Modes ===
{{MOS mode degrees}}


== Theory ==
==== Proposed mode names ====
In contrast to oneirotonic ([[5L 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.
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.

Parasoft checkertonic is the narrow region between 7\19 (442.1¢) and 10\27 (444.4¢).
The [[TAMNAMS]] system is used in this article to refer to {{PAGENAME}} step size ratios and step ratio ranges.

Tunings in this region have a regular temperament interpretation called [[sensi]].
=== Low harmonic entropy scales ===
There are two significant harmonic entropy minima with this MOS pattern:


==Modes==
* [[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.
The modes of checkertonic can be named after its sister MOS [[5L 3s]] (oneirotonic). [[User:R-4981|R-4981]] has also proposed individual names based by chess pieces.
* [[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.
