* [[108:135:160:192]] (1⁄1–5⁄4–[[40/27|40⁄27]]–[[16/9|16⁄9]]) is found on the dominant scale degree (3⁄2 or V) of a diatonic scale with the second degree tuned a comma lower than in Zarlino (10⁄9 instead of 9⁄8), such as in left-handed [[nicetone]].

* [[128:160:192:225]] (1⁄1–5⁄4–3⁄2–[[225/128|225⁄128]]), an inversion of the ''Neapolitan''[https://en.wikipedia.org/wiki/Neapolitan_chord] or ''German sixth''[https://en.wikipedia.org/wiki/Augmented_sixth_chord#German_sixth] chord, is found rooted at [[16/15|16⁄15]] (♭II) and [[8/5|8⁄5]] (♭VI) in the [[duodene]]. (Although ~~225⁄128~~ is often considered an augmented sixth rather than a minor seventh, in [[Meantone_family#Septimal_meantone|septimal meantone]] it is tuned identically to the [[7/4|harmonic seventh]].)
