'''160/81''' is the inversion of the syntonic comma, [[81/80]]. As such, it is very near a full octave. Because "grave" can denote that an interval is lowered by some sort of comma, we can also call this the "classic grave octave." It, being the octave complement of the syntonic comma, can alternatively be given the name "syntonic suboctave"

160/81 is the inversion of the syntonic comma, 81/80. As such, it is very near a full octave. Because "grave" can denote that an interval is lowered by some sort of comma, we can also call this the "classic grave octave." It, being the octave complement of the syntonic comma, can alternatively be given the name "syntonic suboctave"
