HP109-PE – Chapter 5. Changing Various Settings

■

Tuning to other instruments’ pitches (Master

Tuning)

In situations such as when playing ensemble with other

instruments, you can tune the HP109-PE’s standard pitch

to the pitch of another instrument. The standard pitch

generally refers to the pitch of the note that’s played

when you finger the middle A key. This tuning of all the

instruments to a standard pitch is called “tuning.”

If you press the [Piano] button in step 2 of “Making

Detailed Settings (Function)” (p. 29), a display like the

following will appear.

The last three digits are indicated in the display. “440.0

Hz” is indicated in the figure above.

Value 415.3 Hz–440.0 Hz–466.2 Hz

Factory setting 440.0 Hz

This setting remains in effect until you turn off the power.

* You can save this setting in the HP109-PE’s memory using

the Memory Backup function (p. 32).

■

Changing the temperament

You can play classical styles such as Baroque using his-

toric temperaments (tuning methods).

Today, compositions are generally created with equal

temperament in mind and are played using equal tem-

perament. However in past ages of classical music, a vari-

ety 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. 29), a display like the

following will appear.

You can choose from among the eight temperaments

described below.

Factory setting 1 C

Tonic

When playing with tuning other than equal tempera-

ment, 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 holding down the [E. Piano] button, press a note

to specify the desired tonic key.

The tonic note you specify will be displayed as follows.

fig.Chart_note2.j

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

select a tonic note.

* If you record with a temperament other than equal tempera-

ment 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 HP109-PE to the fundamental pitch of the

other instruments.

* You can save this setting in the HP109-PE’s memory using

the Memory Backup function (p. 32).

■

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 “Mak-

ing Detailed Settings (Function)” (p. 29), a display like the

following will appear.

Factory setting On

* This effect works only with the piano tones.

Tempera-

ment

Qualities

1 Equal

In this tuning, each octave is divided into

twelve equal steps. Every interval produces

about the same amount of slight dissonance.

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.

4 Arabic

This tuning is suitable for the music of Ara-

bia.

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).

Temperament Tonic

6 Mean Tone

This scale makes some compromises in just

intonation, enabling transposition to other

keys.

7 Pythagorean

This tuning, devised by the philosopher

Pythagoras, eliminates dissonance in

fourths and fifths. Dissonance is produced

by third-interval chords, but melodies are

euphonious.

Werck-

meister

This temperament combines the Mean Tone

and Pythagorean tunings. Performances are

possible in all keys (first technique, III).

OFF This is the standard tuning curve. This is the right

choice when using Dual performance (p. 20), or

when playing in ensemble with other instru-

ments.

On This tuning curve expands the bass and treble

ends somewhat. It is suitable for performances

such as piano solos.
