Notes on the Use of Classical Temperaments
Using the temperament whose characteristics are best suited for the type of music being played allows one to 
draw even more of the beauty and tension contained in a piece. In particular, employing temperaments that 
can be transposed in pieces featuring modulation results in subtle changes in chords’ resonance, permitting 
alterations in the work’s subtle coloration.
Werckmeister combined with Meantone and Pythagorean scales is one temperament that allows a high degree 
of freedom in modulation, and it has been used in pieces from Bach’s day on into modern times. The 
Kirnberger temperament was also devised with a similar technique, with its use centering on Bach’s organ 
works.
The Meantone temperament, popular throughout Europe during the Baroque period, was commonly used in 
the works of Handel and other Baroque composers, as well as composers of the Renaissance.
In the Middle Ages, Gregorian chants were sung in churches, so the Pythagorean temperament was used due 
to the lengthy reverberation times.
The Vallotti is the most recent of these temperaments. While close to the Equal temperament, it is to a degree 
Just, so it is adaptable to pitches from other instruments, and is often used in today’s ensembles.
Originating in ancient Greece, the Just temperaments, while not well suited for solo passages, can be used 
effectively in cases such as in choral practices for which Just chords are required. In recent years, they have 
come to be used in types of music in which the beauty of such chords is thought to be useful in promoting 
healing.

Changing the Root Note
You must specify the root note to match the key in which you wish to play.
Procedure
Hold down the [Temperament] button, and play the key for the 
desired root note.
fig.02-11
When the power is turned on, the key of C will be selected for the root note.
It is possible to change the root note even when the temperament except for Equal temperament 
is selected. However, for temperaments that allow modulation (Werckmeister, Kirnberger, 
Vallotti, etc.), you will normally use the default setting of C.
The root note that is specified by this operation will not change even if you change the 
temperament. When performing in an ensemble, discrepancies in pitch may result when you 
switch the temperament or the root note. On the C-280, the pitch of other notes is always 
adjusted relative to the pitch of the A note.
Just Major
This is a temperament in which the primary triads are created with a pure third and fifth.
While this temperament provides beautiful chords with no acoustic discrepancy, the considerable 
irregularity of intervals in the scale makes it unsuitable for melodic playing. This acoustic discrepancy is 
especially pronounced between D and A, and between A and C, so no modulation is possible.
Just Minor
As in Just Major, intervals in the primary triads are preserved as pure.
The dissonance of the interval between C and A in Major mode is improved, allowing the primary triads 
to be played in minor mode. The tonic is set to C when the power is turned on, making such chords in C 
minor pure.
