play ment
In this tuning, each octave is divided
into twelve equal steps. Every
1 Equal
interval produces about the same
amount of slight dissonance.
This tuning, devised by the
philosopher Pythagoras, eliminates
Pythagore- dissonance in fourths and fifths.
2
an Dissonance is produced by third-
interval chords, but melodies are
euphonious.
This tuning eliminates ambiguities
in the fifths and thirds. It is unsuited
Just Major to playing melodies and cannot be
3
transposed, but is capable of
beautiful sonorities.
The Just tunings differ from major
and minor keys. You can get the
4 Just Minor
same effect with the minor scale as
with the major scale.
This scale makes some compromises
5 Mean Tone in just intonation, enabling
transposition to other keys.
This temperament combines the
Werckmeis- Mean Tone and Pythagorean
6
ter tunings. Performances are possible
in all keys (first technique, III).
This is an improvement of the Mean
Tone and Just tunings that provides
7 Kirnberger a high degree of freedom of
modulation. Performances are
possible in all keys (III).

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.
* 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.

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."

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.
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.
