== Scales ==
=== 5-note and 6-note (both proper) ===
The 5-note [[MOS]] of slendric is [[1L 4s|Lssss]], in which L is [[7/6]] and s is [[8/7]]; this serves as an approximation to [[5edo]]. This expands to the 6-note MOS, [[5L 1s|LLLLLs]], in which L is 8/7 and s is the characteristic small interval of slendric (sometimes known as the [[quark]]) representing both [[64/63]] and [[49/48]].
Both of these scales are somewhat lacking in harmonic resources relative to similar-sized scales of other temperaments. Even within the 2.3.7 subgroup, [[Superpyth|archy]] and [[Semaphore]] have pentatonic scales with more consonant intervals and chords; or if more accuracy is desired a 2.3.7 [[JI]] scale could be used.
Slendric really shines when used with larger scales than these. The 5-note MOS, however, has a special role in organizing the intervals of slendric because it is so close to [[5edo]] - that is, slendric is very suitable for a pentatonic framework of categorization, rather than a heptatonic/diatonic one.
=== 11-note (LsLsLsLsLss, improper) ===
The 11-note MOS, [[5L 6s|LsLsLsLsLss]], has [[9/8]] "whole tones" in alternation with ~32 cent "sixth tones", with the exception of one pair of adjacent "sixth tones".
