In [[13-limit]] [[just intonation]], '''39/32''', the '''(lesser) tridecimal neutral third''', is the otonal combination of primes 13 and 3 [[Octave reduction||octave-reduced]]. It is the fifth complement of [[16/13]], which measures about 359.5¢.

39/32 differs from the Pythagorean minor third [[32/27]] by [[1053/1024]], about 48¢, from the classic minor third [[6/5]] by [[65/64]], about 27¢, from the rastmic neutral third [[27/22]] by [[144/143]], about 12¢, and from the undecimal neutral third [[11/9]] by [[352/351]], about 4.9¢.

39/32 is a fraction of a cent away from the neutral third found in the 7''n'' family of edos.  
39/32 is a fraction of a cent away from the neutral third found in the 7''n'' family of edos.  
39/32 is near the border-region between neutral thirds and supraminor thirds, so it has a dark edge to it compared to wider neutral thirds, while still sounding slightly brighter than a minor third like [[6/5]].
