Werckmeister IV
Based on five fiths, each reduced of 1/3 of Pythagorean
comma, and two more thirds increased of the same
amount. Very pleasant with mostly unaltered tonalities, it
becomes “harder” as the alterations increase.
Werckmeister V
Based on five fiths reduced by 1/5 of Pythagorean comma,
and one fifth increased of the same amount. This tuning is
rarely used as there is no tonality that is much euphonic.
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.
