[[29edo]] is notable for being the first equal division to have a more precise [[3/2]] than [[12edo]], and the first tuning to be consistent in the [[15-odd-limit]]. 29th-octave temperaments occur naturally when temperament-merging edos whose greatest common divisor is 29.

Copper temperament is derived from a 5-limit comma called [[copper comma]], because it is constructed the same way towards 29edo as [[Kirnberger's atom]] is towards 12edo. A fifth of each of these tunings is modified by a tiny amount, then a circle of these fifths is set to close eventually at the octave.

Surprisingly, despite 29edo's fifth being closer to 3/2 than 12edo's, copper has a higher TE error than [[atomic]] and is not a [[very high accuracy temperaments|very high accuracy temperament]].
It is worth noting that despite 29edo's fifth being closer to 3/2 than 12edo's, copper has a higher TE error than [[atomic]] and hence is not a [[very high accuracy temperaments|very high accuracy temperament]].
