The same idea could also be applied to other equal temperaments, using circles of other intervals, possibly with other equaves. For example: [[George Secor]]'s [[secor29htt|29-tone high tolerance temperament]].

Well temperaments can be obtained by [[detempering]] an equal tuning. This implies going from a [[rank]]-1 temperament to a rank-2 (or higher) temperament by adding one (or more) extra generator(s) — a common choice is to add a pure [[octave]] —, which creates an imperfect generator at the end of the generator chain. Whereas historical well temperaments often make use of irregular patterns of fifth sizes around the circle of fifths, detemperaments have identical generators all along the circle except for the imperfect generator.

If the main generator is a fifth, then there is only one wolf fifth that closes the circle of fifths, a feature which is often associated to tunings such as [[quarter-comma meantone]]. However, these tunings are not always considered as well temperaments because they may not preserve transposability due to their higher mistunings.
