HP103e/102e – 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 HP103e/102e’s standard pitch

to the pitch of another instrument. The standard pitch gener-

ally refers to the pitch of the note that’s played when you fin-

ger 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. 25), 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

Power-up default setting 440.0 Hz

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

Changing the Temperament

You can play classical styles such as Baroque using historic

temperaments (tuning methods).

Today, compositions are generally created with equal tem-

perament in mind and are played using equal temperament.

However in past ages of classical music, a variety of tempera-

ments 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. 25), a display like the fol-

lowing will appear.

fig.disp-temp.j

You can choose from among the seven temperaments

described below.

Power-up default setting 1 C

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.

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 HP103e/102e 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 spe-

cial tuning method for pianos is called “Stretch Tuning.”

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

Detailed Settings (Function) (p. 25), a display like the fol-

lowing will appear.

* This effect works only with the piano tones.

Display Temperament Qualities

1 Equal

In this tuning, each octave is divided into

twelve equal steps. Every interval produces

about the same amount of slight dissonance.

This setting is in effect when you turn on the

power.

2 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.

3 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.

4 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.

Temperament Tonic

5 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).

7 Kirnberger

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).

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

choice when using Dual play (p. 16), or when

playing in ensemble with other instruments.

On This tuning curve expands the bass and treble

ends somewhat. It is suitable for performances

such as piano solos. This setting is in effect when

you turn on the power.
