Performance
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 RM-700 to the fundamental pitch of the other instruments.
Touch <Stretch Tuning> to access the Stretch Tuning screen.
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.

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.)
