KIRNBERGER II
Based on two fifths, reduced by half syntonic
comma, and one fifth reduced by a skisma. There
are three pure majors: C, G, D. Therefore, the
major triads on C and G are pure. Same goes with
the minor triads, on E and B. The four major thirds
on C#, G#, Eb, Bb are Pythagorean. The coexistence
of pure and tempered chords gives a peculiar
character to this tuning.
KELLNER - BACH
This tuning was created by Kellner, who figured out
its structure from the symbols on the first page of
the "Wohltemperierte Klavier" by Bach, 1722. The
tuning is based on five fifths, each reduced of 1/5 of
Pythagorean comma. This originates three
Pythagorean major thirds, on: C#, F#, G#. None of
the thirds is pure. The major third closer to being
pure is on C.
SILBERMANN
Based on fifths reduced of 1/6 of syntonic comma.
Wolf fifth is located on G#. Thirds that in meantone
tuning are pure, here are 1/3 syntonic comma
wider. The wolf fifth is less prominent, not
cacophonic yet not completely acceptable.
