Performing
You can play classical styles such as Baroque using historic
temperaments (tuning methods).
Most modern songs are composed for and played in equal
temperament, the most common tuning in use today. But at
one time, there were a wide variety of other tuning systems in
existence.
By playing in the temperament that was in use when a
composition was created, you can experience the sonorities
of chords originally intended for that song.
This setting applies to all tones.
Setting the Temperament Key
When playing with tuning other than equal temperament,
you need to specify the tonic note for tuning the song to be
performed (that is, the note that corresponds to C for a major
key or to A for a minor key).
If you choose an equal temperament, there’s no need to
select a tonic note.
This setting applies to all tones.
When performing in ensemble with other instruments, be aware
that depending on the key, there may be some shifting of the pitch.
Tune the RK-300 to the fundamental pitch of the other instruments.
Pianos are generally tuned so that the low range is flatter and
the high range is sharper than equal tempered pitches. This
method of tuning is unique to the piano, and is known as
“stretched tuning.”
A graph that shows the changes in pitch of actual tuning
compared with the changes in equal temperament pitch is
called a tuning curve.
Changing the tuning curve produces subtle variations in the
reverberations of the chords you play.
This setting applies only for the front panel [PIANO] button
and for the piano tones Superior Grand and Natural Grand. It
is not available for other tones.
Changing the Tuning (Temperament)
Setting Explanation
Equal
This temperament divides the octave
into 12 equal parts. All intervals will be
slightly out of tune by the same
amount.
Just Major
This temperament makes the 5th and
3rd intervals pure. It is unsuitable for
playing melodies and modulation is
not possible, but it produces
beautifully harmonious chords.
Just Minor
Just intonation differs between major
and minor keys. The same results as
major can be obtained in a minor key.
Arabic
This tuning is suitable for the music of
Arabia.
Kirnberger
This temperament is a modification of
meantone temperament and just
intonation, allowing more freedom of
modulation. It allows you to play in all
keys (third method).
Meantone
This temperament is a partial
compromise of just intonation in order
to allow modulation.
Pythagorean
This temperament is based on the
theories of the Greek philosopher
Pythagoras, and has pure fourths and
fifths. Chords containing a third will
sound impure, but melodies will sound
good.
Werckmeister
This temperament is a combination of
meantone and Pythagorean
temperaments. It allows you to play in
all keys. (First method, number three.)
Setting
C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B
Setting the Tuning Curve
(Stretch Tuning)
Setting Explanation
On
This tuning curve expands the bass and
treble ends somewhat. It is suitable for
performances such as piano solos.
Off
This is the standard tuning curve. It is
suitable when playing in an ensemble with
other instruments.
