The '''311 equal divisions of the octave''' ('''311edo'''), or the '''311(-tone) equal temperament''' ('''311tet''', '''311et''') when viewed from a [[regular temperament]] perspective, a remarkable very high limit equal temperament, [[EDO|dividing the octave equally]] into 311 parts of about 3.86 [[cent]]s each.

~~311EDO~~ is [[consistent]] through the 41-odd-limit and uniquely consistent through the [[23-odd-limit]] and is a [[The Riemann Zeta Function and Tuning #Zeta EDO lists|zeta gap ~~EDO~~]] and a [[The Riemann Zeta Function and Tuning #Zeta EDO lists|zeta peak integer ~~EDO~~]]. It achieves this ~~because~~ except for the prime harmonics greater than 41 (but not including the prime 73 which ''is'' tuned accurately, in fact more accurately than all prior primes), all harmonics up to and including the 80th are more in-tune than out-of-tune with ~~311EDO~~ and thus all the ratios between those harmonics are mapped consistently – and thus with a maximum error of ~1.929¢. This means ~~311EDO~~ is an ''extremely'' efficient temperament for approximating the harmonic series consistently and ''simply'', given how much harmonic content it approximates/represents for its size.
