The down7flat5 chord (odd-limit 9) is also innate-ruyoyo. The interval from 5/4 up to 7/5 is 28/25, equivalent to 9/8. Its homonym is the downadd7upflat5 chord Gbv,7(^b5) = Gb vBb ^Dbb Fb. The upflat five is enharmonically equivalent to an aug 4th = 10/7. | The down7flat5 chord (odd-limit 9) is also innate-ruyoyo. The interval from 5/4 up to 7/5 is 28/25, equivalent to 9/8.

All three of these chords can be voiced to contain the chord shape 4 1 1. This 3-note "nugget" is the essence of the Ruyoyo comma: 9/8 + 5/4 = 7/5. By itself, it's the v,7no5 chord in low-7 voicing. The v7(b5) chord also contains the octave inverse of this nugget, 4 4 1. By itself, this inverse nugget makes Cv(b5) (odd-limit 9). This inverse nugget is also found in Cv,b5 (odd-limit 15), which sounds best in a low-5 voicing. When the added b5 is voiced an 8ve higher, it becomes a v#11, and suggests the vM9,v#11 chord (odd-limit 15). | |||
