Werckmeister temperament
tuning system described by Andreas Werckmeister
English: Werckmeister temperament refers to any of the tuning systems described by Andreas Werckmeister in his writings. The tuning systems are confusingly numbered in two different ways: the first refers to the order in which they were presented as "good temperaments" in Werckmeister's 1691 treatise, the second to their labelling on his monochord. The monochord labels start from III since just intonation is labelled I and quarter-comma meantone is labelled II.
