Viscount Physis Organs Reference Manual
For example, the Kirnberger II temperament is based on the syntonic comma. It spreads the comma equally
between D-A and A-E and the skisma between F# and C#.
A series of three natural major thirds makes a frequency of 5/4^3. The difference between that and the
octave is called enharmonic comma.
When a temperament makes up for more than the Pythagorean comma, usually one fifth is much wider than
the rest and becomes unusable. It is called the wolf fifth.
The circle of fifths of each temperament can start from any key editing the parameter called Base Key.
Follows an explicating graph: in the first half is rapresented Meantone temperament with Base Key set on C,
after on G and finally on B. The second half shows Werkmeister temperament with the same three values of
the Meantone. With the parameter Base Key set to C each temperament is built exactly as shown in the
following circular graphs.
-1/4 sc: a pure fifth narrowed by 1/4 of syntonic comma
-1/4 pc: a pure fifth narrowed by 1/4 of pythagorean comma
