Chapter 3. 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.

This is set to “Equal” when the instrument is turned on.

While holding down the [Metronome] and [Reverb/

Key Touch] buttons, press the appropriate key (F3–B3)

on the keyboard.

You can choose from among the seven temperaments

described below.

■

Setting the 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).

If you choose an equal temperament, there’s no need to select

a tonic note.

While holding down the [Metronome] and [Reverb/

Key Touch] buttons, press the tonic (root) of the key

(C4–B4).

* When performing in ensemble with other instruments, be

aware that depending on the key, there may be some shifting of

the pitch. Tune the HP101 to the standard pitch of the other

instruments.

Qualities

Equal

In this tuning, each octave is divided

into twelve equal steps. Every

interval produces about the same

amount of slight dissonance.

Pythagor

ean

This tuning, devised by the

philosopher Pythagoras, eliminates

dissonance in fourths and fifths.

Dissonance is produced by third-

interval chords, but melodies are

euphonious.

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.

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.

Mean

Tone

This scale makes some compromises

in just intonation, enabling

transposition to other keys.

Werck-

meister

This temperament combines the

Mean Tone and Pythagorean

tunings. Performances are possible in

all keys (first technique, III).

Kirn-

berger

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).
