Changing the Temperament

You can play classical styles such as Baroque using historic
temperaments (tuning methods).
Today, compositions are generally created with equal
temperament in mind and are played using equal
temperament. However in past ages of classical music, a
variety of temperaments were used. Playing a composition
with its original tuning lets you enjoy the sonorities of the
chords that the composer originally intended.
This is set to "Equal" when the instrument is turned on.
1.
While holding down the [Metronome] and [Reverb/
Key Touch] buttons, press the appropriate key (F3–B3)
on the keyboard.
You can choose from among the seven temperaments
described below.
Temper-
Key Qualities
ament
In this tuning, each octave is divided
into twelve equal steps. Every
F3 Equal
interval produces about the same
amount of slight dissonance.
This tuning, devised by the
philosopher Pythagoras, eliminates
Pythagor dissonance in fourths and fifths.
F 3
ean Dissonance is produced by third-
interval chords, but melodies are
euphonious.
This tuning eliminates ambiguities in
the fifths and thirds. It is unsuited to
Just
G3 playing melodies and cannot be
Major
transposed, but is capable of
beautiful sonorities.

■ Setting the 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).
If you choose an equal temperament, there's no need to select
a tonic note.
1.
While holding down the [Metronome] and [Reverb/
Key Touch] buttons, press the tonic (root) of the key
(C4–B4).
* When performing in ensemble with other instruments, be
aware that depending on the key, there may be some shifting of
the pitch. Tune the HP101 to the standard pitch of the other
instruments.

Qualities
The Just tunings differ from major
and minor keys. You can get the
same effect with the minor scale as
with the major scale.
This scale makes some compromises
in just intonation, enabling
transposition to other keys.
This temperament combines the
Mean Tone and Pythagorean
tunings. Performances are possible in
all keys (first technique, III).
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).
