"Well tempered" means that the twelve notes per octave

Key (music)
In music theory, the term key is used in many different and sometimes contradictory ways. A common use is to speak of music as being "in" a specific key, such as in the key of C major or in the key of F-sharp. Sometimes the terms "major" or "minor" are appended, as in the key of A minor or in the...

, the well temperament was first invented by the Chinese prince of the Ming dynasty Chu Tsai-Yü in 1584 and came in contact with Western culture during exchange fairs organized by the Cantonese viceroy in that time. How exactly it travelled to Europe is not documented, but it is likely that Jesuits in China brought the knowledge over to Europe (Temple 2007). Other scholars, however, state that Prince Chu accurately calculated not a well temperament but equal temperament

 (1548–1620) wrote an essay containing the correct mathematical formulation of equal temperament for the first time in Western musical theory, though his manuscript remained unpublished until long after the author's death (Kutter 1975, 167–68; Stevin 1884).

Forms

The term "well temperament" usually means some sort of irregular temperament in which the tempered fifths are of different sizes but no key has very impure intervals. Historical irregular temperaments usually have the narrowest fifths between the diatonic notes ("naturals") producing purer thirds, and wider fifths among the chromatic notes ("sharps and flats"). Each key then has a slightly different intonation, hence different keys have distinct characters. Such "key-color" was an essential part of much 18th- and 19th-century music and was described in treatises of the period.

The first circular temperament was described by the organist Arnolt Schlick

, others nearer equal temperament. Although such tunings have no wolf fifth, keys with many sharps or flats still do not sound very well in tune (due to their thirds), and can only be used fleetingly. Some theorists have sought to define "well temperament" more narrowly to exclude fifths wider than pure, which rules out many such schemes.
