Changing Various Settings
■
Changing the Temperament
You can play classical styles such as Baroque using historic
temperaments (tuning methods).
Today, compositions are generally created with equal
temperament in mind and are played using equal
temperament. However in past ages of classical music, a
variety of temperaments were used. Playing a composition
with its original tuning lets you enjoy the sonorities of the
chords that the composer originally intended.
If you press
the [E.Piano] button
in step 2 of “Making
Detailed Settings (Function)” (p. 31), a display like the
following will appear.
fig.disp-temp.e
You can choose from among the seven temperaments
described below.
Power-up default setting
1 C
Tonic
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).
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.e
If you choose an equal temperament, there’s no need to select
a keynote.
* 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-900 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.”
If you press
the [Harpsichord] button
in step 2 of “Making
Detailed Settings (Function)” (p. 31), a display like the
following will appear.

OFF This is the standard tuning curve. This is the right
choice when using Dual play (p. 17), or when playing
in ensemble with other instruments.
On This tuning curve expands the bass and treble ends
somewhat. It is suitable for performances such as
piano solos. This setting is in effect when you turn on
the power.

Temperament Qualities
1
Equal In this tuning, each octave is di-
vided into twelve equal steps.
Every interval produces about
the same amount of slight disso-
nance. This setting is in effect
when you turn on the power.
2 Pythagorean This tuning, devised by the phi-
losopher Pythagoras, eliminates
dissonance in fourths and fifths.
Dissonance is produced by
third-interval chords, but melo-
dies are euphonious.
3 Just Major This tuning eliminates ambigu-
ities 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 ma-
jor 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 compro-
mises in just intonation, enabling
transposition to other keys.
6 Werckmeister
This temperament combines the
Mean Tone and Pythagorean tun-
ings. Performances are possible
in all keys (first technique, III).
7 Kirn-berger This is an improvement of the
Mean Tone and Just tunings that
provides a high degree of free-
dom of modulation. Performanc-
es are possible in all keys (III).
