It arises in just intonation scales often as the octave complement of [[980/729]].  
It arises in just intonation as the difference between the semidimished fourth [[35/27]] and the supermajor seventh [[27/14]], making it a critical tempering target in the [[Canovian chord]]. However, its distinction from 3/2 is emphasised in the [[canou family]] of temperaments, through its accessibility by two steps of the [[81/70]]-generator.
