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
Power-up default setting 440.0 Hz
This setting remains in effect until you turn off the power.
I 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.

Temperament
You can choose from among the seven temperaments
described below.
Display Temperament
In this tuning, each octave is divided into
twelve equal steps. Every interval produces
1 Equal about the same amount of slight dissonance.
This setting is in effect when you turn on the
power.
This tuning, devised by the philosopher
Pythagoras, eliminates dissonance in
2 Pythagorean fourths and fifths. Dissonance is produced
by third-interval chords, but melodies are
euphonious.
This tuning eliminates ambiguities in the
fifths and thirds. It is unsuited to playing
3 Just Major
melodies and cannot be transposed, but is
capable of beautiful sonorities.
The Just tunings differ from major and
4 Just Minor minor keys. You can get the same effect with
the minor scale as with the major scale.

Qualities
Display Temperament
This scale makes some compromises in just
5 Mean Tone intonation, enabling transposition to other
keys.
This temperament combines the Mean Tone
Werck-
6 and Pythagorean tunings. Performances are
meister
possible in all keys (first technique, III).
This is an improvement of the Mean Tone
and Just tunings that provides a high degree
7 Kirnberger
of freedom of modulation. Performances are
possible in all keys (III).
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.

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.
I 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.

Values
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.
Power-up default setting On
* This effect works only with the piano tones.
