Well temperament

A well temperament is a circulating temperament where the intervals in a class are not all tuned the same. As a consequence of their irregularity, it is possible in extreme cases for well temperaments to have classes where they tune each instance of an interval in that class uniquely, as if they were just scales of the same rank as their cardinality.
