Various Settings
You can adjust the volume balance between the two tones (tone 1
and tone 2) used for Dual play.
When playing ensemble with other instruments and in other such
instances, you can match the standard pitch to another instrument.
The standard pitch generally refers to the pitch of the note that’s
played when you finger the middle A key. For a cleaner ensemble
sound while performing with one or more other instruments, ensure
that each instrument’s standard pitch is in tune with that of the
other instruments. This tuning of all the instruments to a standard
pitch is called “Tuning.”
When the instrument is shipped from the factory, this is set to
“440.0 Hz.”
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.”
You can play classical music such as baroque pieces using their
original tuning.
Most modern songs are composed and played with the assumption
that equal temperament (the most common tuning in use today)
will be used, but when classical music was composed, there were a
wide variety of other tuning systems in existence. Playing a
composition with its original tuning lets you enjoy the sonorities of
the chords that the composer originally intended.
When playing with tuning other than equal temperament, you need
to specify the temperament key 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 temperament key.
* When performing in ensemble with other instruments, be aware
that depending on the key, there may be some shifting of the pitch.
Tune the HP305/HP302 to the fundamental pitch of the other
instruments.

Setting Description
On
This tuning curve expands the bass and treble ends
somewhat. It is suitable for performances such as
piano solos.
OFF
This is the standard tuning curve. This is suitable for
when using Dual play (p. 31) or when playing in an
ensemble with other instruments.

Adjusting the Tuning (Temperament)
Setting 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.
2 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.
3 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 Arabia.
5 Kirnberger
This is an improvement of the Meantone and
Just tunings that provides a high degree of
freedom of modulation. Performances are
possible in all keys (
III ).
6 Meantone
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.
8 Werckmeister
This temperament combines the Meantone and
Pythagorean tunings. Performances are
possible in all keys (first technique,
III ).
