'''6:7:9''', a ''subminor triad'' or ''septimal minor triad'', is a triad in the [[7-limit]] sometimes used in place of a [[minor triad]]. It appears as a minor triad in the [[5L 2s|diatonic scale]] of [[superpyth]], as [[64/63]] being tempered out means [[32/27]] is equated with [[7/6]]. This is in contrast to [[meantone]], where 32/27 is equated with [[6/5]], and thus the minor triad becomes [[10:12:15]].

6:7:9 is the second-simplest [[otonal]] triad ~~of the form Root-3rd-P5~~, past [[4:5:6]], and is thus very [[consonant]]. However, its inverse, [[14:18:21]], may sound less stable due to its higher otonal complexity. In addition, the [[7/6]] and [[9/7]] intervals differ by [[54/49]], an interval of 168 [[cent]]s, which means the subminor and supermajor triads don't contrast very well the same way 5-limit triads do. Nonetheless, these triads may be used in progressions together with the 5-limit ones.
