'''[[Ed12|Division of the twelfth harmonic]] into 129 equal parts''' (129ED12) is very nearly identical to [[36edo|36 EDO]] (sixth-tone tuning), but with the [[12/1]] rather than the 2/1 being just. The octave is about 0.55 [[cent]]s stretched and the step size is about 33.35 cents.

129ed12 is very nearly identical to [[36edo]] (sixth-tone tuning), but with the 12th harmonic rather than the [[2/1|octave]] being just. This stretches the octave by about 0.546{{c}}. The local [[The Riemann zeta function and tuning #Optimal octave stretch|zeta peak]] around 36 is located at 35.982388, which has a step size of 33.3496{{c}} and has octaves stretched by 0.587{{c}}; 129ed12's octave is extremely close to optimal, being only 0.0418{{c}} ({{sfrac|1|23}} of a cent) off from the zeta peak.

Since 129 factors into primes as {{nowrap| 3 × 43 }}, 129ed12 contains subset ed12's [[3ed12]] and [[43ed12]].
