Chapter 5. Changing Various Settings
Power-up default setting
1 C
Tonic
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).
While hold down
the [E. Piano] button
, and press
a note
to
specify the desired tonic key.
The tonic note you specify will be displayed as follows.
fig.Chart_note2.j
If you choose an equal temperament, there’s no need to select
a tonic note.
* If you record with a temperament other than equal
temperament selected, and then want to play back that
performance, use this setting to select the same temperament
for playback as the temperament you used when recording.
* When performing in ensemble with other instruments, be
aware that depending on the key, there may be some shifting of
the pitch. Tune the DP-970 to the fundamental pitch of the
other instruments.

Setting the Tuning Curve
(Stretch Tuning)
A piano is generally tuned to a pitch with a lower bass range
and a higher treble range than equal temperament. This
special tuning method for pianos is called “Stretch Tuning.”

Hold down the [Split] button, and press the [Reverb]
button.
The DP-970 switches to the function mode.

Press the [Harpsi] button.
The button’s indicator flashes.

Qualities
1
Equal
In this tuning, each octave is divided
into twelve equal steps. Every
interval produces about the same
amount of slight dissonance.
2
Pythagore-
an
This tuning, devised by the
philosopher Pythagoras, eliminates
dissonance in fourths and fifths.
Dissonance is produced by third-
interval chords, but melodies are
euphonious.
3
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.
4
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.
5
Mean Tone
This scale makes some compromises
in just intonation, enabling
transposition to other keys.
6
Werckmeis-
ter
This temperament combines the
Mean Tone and Pythagorean
tunings. Performances are possible
in all keys (first technique, III).
7
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 (III).

OFF
This is the standard tuning curve. This is the
right choice when using Dual play (p. 26), or
when playing in ensemble with other instru-
ments.
On
This tuning curve expands the bass and tre-
ble ends somewhat. It is suitable for perfor-
mances such as piano solos. This setting is in
effect when you turn on the power.
