Changing the Tuning (Tuning)

❍

Choosing the Tuning

You can play classical styles such as Baroque using historic

temperaments (tuning methods).

Most modern songs are composed for and played in equal

temperament, the most common tuning in use today. But at

one time, there were a wide variety of other tuning systems

in existence. By playing in the temperament that was in use

when a composition was created, you can experience the

sonorities of chords originally intended for that song.

At Step 3 in “Procedure” (p. 152), touch <Tuning>.

fig.d-p-temp.eps_50

You can choose from among the eight tunings described

below.

Touch any one of the icons to choose the tuning system.

When playing in a temperament other than equal

temperament, you must specify the tonic (the note

corresponding to C for a major key, or to A for a minor key)

of the key in which you will play.

Touch <Key> to select the tonic.

If you have selected equal temperament, it is not necessary to

select the tonic.

❍

Setting the Tuning Curve (Stretch Tuning)

Pianos are generally tuned so that the low range is flatter and

the high range is sharper than equal tempered pitches. This

method of tuning is unique to the piano, and is known as

“stretched tuning.”

A graph that shows the changes in pitch of actual tuning

compared with the changes in equal temperament pitch is

called a tuning curve. Changing the tuning curve produces

subtle variations in the reverberations of the chords you play.

Touch the Stretch Tuning <ON> or <OFF> icon to select the

tuning curve.

When set to “ON,” the tuning curve features extended low

and high ranges (Stretch Tuning). It is suitable for piano

solos. This setting is selected when the power is turned on.

When set to “OFF,” the standard tuning curve is used. It is

suitable when playing in an ensemble with other

instruments.

Characteristics

Equal

This temperament divides the octave

into 12 equal parts. All intervals will be

slightly out of tune by the same amount.

This setting is in effect when you turn on

the power.

Just (Maj)

This temperament makes the 5th and

3rd intervals pure. It is unsuited to

playing melodies and cannot be

transposed, but is capable of beautiful

sonorities.

Just (min)

Just intonation differs between major

and minor keys. The same results as

major can be obtained in a minor key.

Arabic

This tuning is suitable for the music of

Arabia.

Kirnberger

This temperament is a modification of

meantone temperament and just

intonation, allowing more freedom of

modulation. Performances are possible

in all keys (III).

Pythagorean

This temperament is based on the

theories of the Greek philosopher

Pythagoras, and has pure fourths and

fifths. Chords containing a third will

sound impure, but melodies will sound

good.

Meantone

This temperament is a partial

compromise of just intonation in order

to allow modulation.

Werkmeister

This temperament is a combination of

meantone and Pythagorean

temperaments. It allows you to play in

all keys. (First method, number three.)
