Tuning to Other Instruments’ Pitches
(Master Tuning)
In situations such as when playing ensemble with other instruments,
you can tune the HPi-7S’s standard pitch to the pitch of another
instrument. 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. The standard pitch
generally refers to the pitch of the note that’s played when you finger
the middle A key.
■
Changing the Tuning (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. By playing in
the temperament that was in use when a composition was created,
you can experience the sonorities of chords originally intended for
that song.
When performing in ensemble with other instruments, be
aware that depending on the key, there may be some
shifting of the pitch. Tune the HPi-7S to the fundamental
pitch of the other instruments.
■
Setting the Tonic (Key)
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.

Explanation
Equal
This temperament divides the octave into 12
equal parts. All intervals will be slightly out of
tune by the same amount.
Just (Maj)
This temperament makes the 5th and 3rd
intervals pure. It is unsuitable for playing
melodies and modulation is not possible, but it
produces beautifully harmonious chords.
Just (min)
Just intonation differs between major and minor
keys. The same results as major can be
obtained in a minor key.
Arabic
This tuning is suitable for the music of Arabia.
Kirnberger
This temperament is a modification of
meantone temperament and just intonation,
allowing more freedom of modulation. It allows
you to play in all keys (third method).
Pythagorean
This temperament is based on the theories of
the Greek philosopher Pythagoras, and has
pure fourths and fifths. Chords containing a
third will sound impure, but melodies will
sound good.
Meantone
This temperament is a partial compromise of
just intonation in order to allow modulation.
Werkmeister
This temperament is a combination of
meantone and Pythagorean temperaments. It
allows you to play in all keys. (First method,
number three.)
