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