	'''140:180:210:252:315''' is the ''subharmonic ninth chord''. It is a septimal ''dominant ninth chord''. It is the inverse of [[4:5:6:7:9]], and can serve as the fundamental utonal consonance of the 9-odd-limit, with many chords being a subset of it or one of its inversions. Its otonal inverse, [[4:5:6:7:9]], can also be seen as a fundamental chord, and subsets can be taken out of it as well. The 1/(9:7:6:5:4) chord can be modified to get its otonal inverse by inflecting both the third and seventh down by [[36/35]], so the third becomes [[5/4]] and the seventh [[7/4]].
