MEANTONE
- 8 pure major thirds: E flat - G / B flat - D / F - A / C - E / G - B / D - F # / A - C# / E - G.
- 4 unusable major thirds (diminished fourths): B - D# / F# - A# / C# - E# / A flat - C.
- 1 fifth known as the “wolf” (very dissonant extended fifth): A flat - E flat.
- Highly irregular chromatic scale (meaning that chromatic compositions are given a very distinctive voice)
- Keys usable with this temperament: C maj. / D maj. / G maj. / A maj. / B flat maj. and the relative minors.
The temperaments which follow allow all the major and minor keys to be used, although those with the most alterations have
a highly distinctive voice, in contrast with the modern equal temperament.
WERCKMEISTER
This temperament, invented by the organist and musical theorist Andreas Werckmeister, is recommended for performing the
German musical repertoire of the late 1600s.
KIRNBERGER
This temperament, developed by Johann Philipp Kirnberger, pupil of J.S. Bach, is also suitable for playing the German
baroque composers and the works of Bach.
PYTHAGOREAN
In this temperament, all the fifths are natural except for the “wolf” fifth, in the interval A flat - E flat, which is greatly
diminished.
It dates from the Middle Ages up to the 15th century, and can therefore be used for compositions of that period.
VALLOTTI
This Italian temperament invented by Francescantonio Vallotti was later taken up in England by Thomas Young. It can be
used effectively for the Italian 18th Century repertoire, and also for the English repertoire of the same period.
