Settings
You can play classical music such as baroque pieces using
their original tuning.
Most modern songs are composed and played with the
assumption that equal temperament (the most common tuning
in use today) will be used, but when classical music was
composed, there were a wide variety of other tuning systems
in existence. Playing a composition with its original tuning lets
you enjoy the sonorities of the chords that the composer
originally intended.

You can choose from among the seven tunings
described below.
Specifying the Keynote
When playing with tuning other than equal temperament, you
need to specify the keynote 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 keynote.

Hold down the [Piano] button and use the [-]

When performing in ensemble with other
instruments, be aware that depending on the key,
there may be some shifting of the pitch. Tune the FP-4
to the fundamental pitch of the other instruments.
Adjusting the Tuning (Temperament)
Display Temperament Description
1 Equal
In this tuning, each octave is divided
into twelve equal steps. Every interval
produces about the same amount of
slight dissonance. This setting is in
effect when you turn on the power.
2 Just Major
This tuning eliminates ambiguities in
the fifths and thirds. It is unsuited to
playing melodies and cannot be
transposed, but is capable of
beautiful sonorities.
3 Just Minor
The Just tunings differ from major and
minor keys. You can get the same
effect with the minor scale as with the
major scale.
Temperament Keynote
4 Kirnberger
This is an improvement of the Mean
Tone and Just tunings that provides a
high degree of freedom of
modulation. Performances are
possible in all keys (third method).
5 Mean Tone
This scale makes some compromises
in just intonation, enabling
transposition to other keys.
6 Pythagorean
This tuning, devised by the
philosopher Pythagoras, eliminates
dissonance in fourths and fifths.
Dissonance is produced by third-
interval chords, but melodies are
euphonious.
7 Werckmeister
This temperament combines the Mean
Tone and Pythagorean tunings.
Performances are possible in all keys
(first method, number three).
