Playing <Basic Operation>
If you’re playing the C-230 together with other instruments in an ensemble, you can adjust the pitch of the C-230 to match the
other instruments if necessary.
You can adjust the C-230’s reference pitch by choosing one of three fixed settings: A= 440Hz (default), 415Hz (Baroque pitch)
or 392Hz (Versailles pitch).
•When you turn on the power, the pitch is set to 440Hz (the “440Hz” indicator lights).
Press the [Pitch] button repeatedly until the indicator of the
desired pitch lights.
The C-230 allows you to easily change the temperament. By using historical temperaments to play music that is appropriate for
the characteristics of each temperament, you can more strongly bring out the beauty or tension inherent in a composition. In
particular, when playing a composition that uses a transposable temperament and includes transpositions, the sonority of the
chords will change when a transposition occurs, creating subtle changes in the coloration of the piece.
“Werckmeister” is a temperament that combines Meantone and Pythagorean scales to enhance the degree of transposability, and
has been used ever since Bach up to the present. “Kirnberger” was conceived using similar methods, and is used mainly when
playing the organ works of Bach.
“Vallotti” is the most recent of the temperaments described here. It is close to equal temperament, but since it is somewhat pure,
it blends easily with other instruments, and today is often used in ensembles.
Meantone was popular throughout Europe during the Baroque era, and was used customarily by Baroque musicians such as
Handel as well as in compositions of the Renaissance period.
Press the [Temperament] button repeatedly until the indicator
of the desired temperament lights.
If you proceed past Meantone, you will “wrap around” to
Equal.
The [Temperament] button only lights when a temperament
other than “Equal” is selected.
“Equal” will be selected every time the power is turned on.
The difference between the various temperaments may not always be obvious.
