Just Minor
Intonation (JustMin) This temperament arranges just major intonation to
provide perfect harmony within a single tonality (minor
key). Within the 12 notes, 11 of the notes are the same
pitch as just major intonation.
Pythagorean System
(Pythago) This temperament, which uses a 12-note octave, is
thought to be the oldest. Of the 12 types of perfect fifths
that can be played, 11 are in perfect harmony. Thirds are
unharmonious and dissonant, and are appropriate for
melody play.
Mean – Tone System
(Mean) This highly practical temperament provides many of the
merits (beautiful triads) of just intonation, plus
modulation capabilities. It was used as a keyboard tuning
method for a long period following the Renaissance.
Werckmeister
(Werck) This is a kind of unequal temperament that allows play of
all tonality. It is believed that Bach’s “The Well-Tempered
Clavier” was written using this temperament. Using a
root of C makes the dominant tonality of the white keys
close to mean-tone, and the dominant tonality of the
black keys close to Pythagorean System.
Kirnberger (Kirnber) This is also a type of unequal temperament, which is also
similar to the Werckmeister tuning described above. The
chromatic differential of the white key dominant tonality
and black key dominant tonality is more pronounced.
Temperament Root
(Temp Root) C, C#, D, Eb, E, F, F#,
G, Ab, A, Bb, B Specifies the root of a temperament. The initial default
setting is C. Selecting a different root for equal
temperament does not make a difference in the sound,
but a difference can be noted with classical
temperaments. For classical temperaments other than
Werckmeister and Kirnberger, specify the tonality
keynote of the piece you are playing when using a
classical temperament.
