In this tuning, each octave is divided

into twelve equal steps. Every

interval produces about the same

 

 

 

 

amount of slight dissonance.

philosopher Pythagoras, eliminates

Dissonance is produced by third-

This tuning eliminates ambiguities

beautiful sonorities.

 

 

 

 

 

The Just tunings differ from major

This temperament combines the

in all keys (first technique, III).

 

 

 

 

 

This is an improvement of the Mean

possible in all keys (III).

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.

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.”

1.Hold down the [Split] button, and press the [Reverb] button.

The DP-970 switches to the function mode.

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

This is the standard tuning curve. This is the

OFF

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-

On

ble ends somewhat. It is suitable for perfor-

mances such as piano solos. This setting is in

 

 

effect when you turn on the power.
