The second comma in the comma list determines how we extend the no-3 subgroup temperament to include the harmonic 3.

=== | ==== Subgroup extensions ==== | ||
When extending to the 2.5.7.11.13 subgroup, two strong extensions are considerable: ''valimar'' and ''valarin'', considered in [[#Subgroup extensions_2|#Subgroup extensions]]; they intersect in [[hemimean clan #tridecimal didacus|tridecimal didacus]]. | |||

Named by [[Xenllium]] in 2026, augenic is closely related to [[augene]]. It tempers out the [[augmented comma]] but with a free generator for [[7/1|7]], and then extends it to the 11-limit through the identity [[128/125]] = ([[56/55]])⋅(176/175). | Named by [[Xenllium]] in 2026, augenic is closely related to [[augmented family #Septimal augmented (augene)|augene]].

=== Valimar (2.5.7.11.13) === | |||
This extension to the no-threes 13-limit is motivated by extending the valinorsmic chain of 5/4's, where two form 11/7, so that four form 16/13. This logic is supported by rank-2 temperaments such as tridecimal didacus and the 13-limit [[sensamagic clan #Magus|magus]]/[[starling temperaments #Amigo|amigo]] extensions, as well as [[semicomma family #Winston|winston]] and [[gamelismic clan #Valentino|valentino]]. This is also natural considering [[S-expression]]s, noting that 176/175 (S8/S10) is nontrivially equivalent to (S11⋅S12)/(S14⋅S15), and this extension tempers out [[1573/1568]] (S11/S14), and [[3584/3575]] (S12/S15). It remains well-tuned in equal temperaments with optimal valinorsmic 5/4's (such as [[37edo|37]], [[40edo|40]], and [[43edo|43]]). | |||

=== Valarin (2.5.7.11.13) === | |||
This extension equates two, ideally slightly flattened, [[8/7]]'s to [[13/10]], which is also natural given valinorsmic's tuning tendency towards sharpening [[7/4]]. This extension is supported by rank-2 temperaments including tridecimal didacus, [[semicomma family #Orwell|tridecimal orwell]], [[gamelismic clan #Lupercalia|lupercalia]] (an extension of [[gamelismic clan #valentine|valentine]]), and [[no-threes subgroup temperaments #Llywelyn a.k.a. shoe|llywelyn]]. | |||
