Matching the Pitch with Other Instruments
(Master Tuning)
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."
Setting Master tuning value
15.3–40.0–66.2 415.3 Hz – 440.0 Hz – 466.2 Hz
When the instrument is shipped from the factory, this is
set to "440.0 Hz."
Using a Piano's Unique Tuning
(Stretch Tuning)
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."
Setting Description
This tuning curve expands the bass and treble
On ends somewhat. It is suitable for performances
such as piano solos.
This is the standard tuning curve. This is suitable
OFF for when using Dual play (p. 28) or when playing
in an ensemble with other instruments.

Adjusting the Tuning (Temperament)

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.
Temperament Temperament key
Setting Temperament Qualities
In this tuning, each octave is divided into
twelve equal steps. Every interval
1 Equal
produces about the same amount of
slight dissonance.
This tuning eliminates ambiguities in the
fifths and thirds. It is unsuited to playing
2 Just (Major)
melodies and cannot be transposed, but
is capable of beautiful sonorities.
The Just tunings differ from major and
minor keys. You can get the same effect
3 Just (Minor)
with the minor scale as with the major
scale.
This tuning is suitable for the music of
4 Arabic
Arabia.
This is an improvement of the Meantone
and Just tunings that provides a high
5 Kirnberger
degree of freedom of modulation.
Performances are possible in all keys (III).
This scale makes some compromises in
6 Meantone just intonation, enabling transposition to
other keys.
This tuning, devised by the philosopher
Pythagoras, eliminates dissonance in
7 Pythagorean fourths and fifths. Dissonance is produced
by third-interval chords, but melodies are
euphonious.
This temperament combines the
Meantone and Pythagorean tunings.
8 Werckmeister
Performances are possible in all keys (first
technique, III).
