Preset Temperament Introduction
Equal Equal is the temperament that divides an octave into 12 equal intervals. This temperament has only one
semitone and one equitonic, which is very convenient for transposition. Equal is currently the internation-
al standard tuning for keyboard instruments.
Pure Major The just intonation is any musical tuning which is based on the stack of intervals called perfect fth and
major third of overtone series. Pure Major & Minor works best when music uses extensive harmony, such
as vocal harmony or cantata styles.
Because there are two kinds of full tone and half tones in the temperament, it is not generally suitable for
keyboard instrument performance.
Pure Minor
Pythagorean Pythagorean is the oldest temperament in the world, also called Circle-of-fths. This system was rst
devised by Pythagoras and was later named after him.
The Pythagorean temperament comes from a circle-of-fths system. Compared with Equal, Pythagorean
has a larger full tone and smaller half tone.
Mean-Tone The Mean-tone was put forward for the practical application of the Pure temperament for keyboard
instruments. Its characteristic is very close to the consonance of Pure temperament when forming triads.
It was popular in Europe for hundreds of years because of its simpler structure than Pure temperament.
Werckmeister Werckmeister is an improvement on the Pythagorean proposed by Andreas Werckmeister, a German
organist and music theorist.
The fth interval of Werckmeister retains the essence of natural law and it can play twelve major and
minor keys without retuning. Bach called it the temperament closest to Well-Tempered.
Under this temperament, each tonal feature has distinct colors. This is an important basis for classical
and romantic music which names the melody with the tonal name, and also the biggest reason for the
revival of the classical temperament.
Kirnberger Kirnberger was proposed by Johann Philippe Kirnberger, a student of Bach. After verifying the tempera-
ment used in Bach’s Well-Tempered Clavichord, he standardized it as a new temperament.
This temperament is a mixture of the “Mean-tone” and “Pure” temperaments. It is considered an im-
provement on the”Mean-tone temperament”.
