| Chord information |
128:160:192:225, a German sixth chord, is found rooted at the ♭II (16⁄15) and ♭VI (8⁄5) of the duodene.
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 and marvel 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 (12edo and its multiples) it is tuned identically to 36:45:54:64 and 20:25:30:36.
If 128/125 is tempered out, this chord is tuned identically to both 256:320:375:450 and 20:25:30:36.
