'''128:160:192:225''', a [[5-limit]] interpretation of an inversion of the {{w|Neapolitan chord|''Neapolitan''}} or {{w|Augmented sixth chord #German sixth|''German sixth chord''}}, is found rooted at the ♭II ({{Frac|16|15}}) and ♭VI ({{Frac|8|5}}) of the [[duodene]].

[[225/128]] is ~~often~~ considered an augmented sixth rather than a minor seventh, ~~and especially~~ in [[septimal meantone]] it is tuned identically to [[7/4]], so that the ~~chord reduces~~ to ~~the much simpler~~ [[4:5:6:7]]~~. However, chords employing it may still be considered a kind of~~ [[~~dominant seventh chord~~]].

[[225/128]] is usually considered an augmented sixth rather than a minor seventh; however, it is often tempered in a way that makes this chord indistinguishable from certain kinds of [[dominant seventh chord]]. For example, in [[septimal meantone]] it is tuned identically to the much simpler harmonic seventh chord [[4:5:6:7]], and in meantone tunings that also temper out the [[Pythagorean comma]] (such as [[12edo]] and its multiples) it is tuned identically to [[36:45:54:64]] and [[20:25:30:36]].
