== Chords and harmony ==
The fundamental consonances of this subgroup may be taken to be [[4:7:10]] and [[14:20:35]]. The otonal chord is [[DR]] and the utonal chord is the inverse of the otonal chord, similar to [[4:5:6]] and [[10:12:15]] in the [[5-limit]]. They are bounded by [[5/2]] and the middle voices contrast by [[49/40]].
4:7:10 may be extended to [[4:7:10:13]], preserving the DR property and implying adding prime [[13/1|13]] to this subgroup.
