This is the subharmonic sixth added-eleventh chord cuz it extends the subharmonic sixth chord. "Minor sixth chord" is confusing.

'''1/(24:20:16:14:9)''', a ''minor sixth added-eleventh chord'', is a [[pentad]] in [[7-limit]] harmony. 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.

1/(24:20:16:14:9), a subharmonic sixth added-eleventh chord, is a pentad in 7-limit harmony. It extends the subharmonic sixth chord, 1/(12:10:8:7). 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.

This chord has a similar shape to 4:5:6:7:11, and can be obtained by inflecting the 5/4 down by 25/24, the 7/4 down by 49/48, and the 11/4 down by 33/32.
