Roland HP 2700 - Playing Using Classical Tuning; Changing the Tonic

Playing Using Classical Tuning
Your new piano allows you to play classical
music, such as baroque, while tuned in a manner
common to that age.
TEMPERAMENT refers to the method of tuning used.
In modern times, most music is written with Equal Tem-
perament in mind. During the course of the development
of classical music, however, a number of other forms of
tuning were also in common use. By playing while tuned
in the manner which was correct for the period, you
will be able to enjoy the sonorities that the chords in
a particular piece were originally meant to have.
@ Press the TEMPERAMENT button.
The indicator on the TEMPERAMENT button
will light. One of the Voice buttons will start
blinking. In this case, it represents the type
of tuning that is active at that time.
@ While continuing to hold down the TEMPER-
AMENT button, press the Voice button that
corresponds to the temperament you wish
to use.
Once a setting for a temperament other
than Equal has been made, the TEMPERA-
MENT button can thereafter be used to
switch between Equal temperament and the
other selected tuning.

@ Equal Temperament
12-tone equal temperament. The temperament most
commonly used today.
@ Pythagorean Temperament
Developed by the philosopher Pythagoras as a method
of tuning which resolved the ambiguity of fourths and
fifths. As a result melodies sound cleaner, but a certain
amount of ambiguity is produced with triads.
@ Just Temperament
A method of tuning which resolved the ambiguity of
fifths and thirds. Quite beautiful sonorities are pro-
duced with chords, but the scale is unbalanced and is
thus not well-suited for melodies.
2. Adjusting to Suit Your Preferences
[Changing the Tonic]
@ With the Major Scale
While holding down the TEMPERAMENT button, press
the keynote for the key. (For C major, this is C.)
When wishing to play a piece in A major:
o The keynote for A major is the note of A. So,
while holding down the TEMPERAMENT but-
ton, press the A note.
@ With the Minor Scale
While holding down the TEMPERAMENT button, press
the note which is the keynote for a key that has an
identical number of sharps and flats as the key in
question.
However, when using Just temperament, the manner
in which the setting is made differs, due to the need
for differentiating between major and minor keys and
sounding the principal triads in compliance with Just
temperament.
While holding down the TEMPERAMENT button, press
the keynote for the key, along with the key which is a
minor third above.
When wishing to play a piece in the key of
C minor (With temperaments other than Just)
The key which has an identical number of # and
b as Cm is the E-flat major key. The keynote for
the E-flat major key is Eb.
So, while holding down the TEMPERAMENT
button, press the Eb key.
When wishing to play a piece in the key of
C minor (With Just temperament)
The keynote of Cm is C, and the key a minor
third above is Eb. So, while holding down the
TEMPERAMENT button, press the C and Eb keys.
* Once a setting for the tonic has been made, it will not change
even if you change temperaments.
* When you have selected a temperament other than Equal and
play in ensemble with other instruments, certain discrepancies
in pitch may be noticed, depending on the key being used. In
such cases, use the Tuning knob to adjust the pitch so it
matches the tonic for the other instruments.
@ Mean Tone Temperament
A temperament which adds some compromises to Just
temperament, and facilitates transposition.
@ Werckmeister Temperament
(The 3rd scale within the first group of scales)
Through combining the Mean Tone and Pythagorean
temperaments, it allows for playing in any key.
@ Kirnberger Temperament (The 3rd scale)
As a result of improvements made to the Mean Tone
and Just temperaments, it is relatively tolerant towards
transposition, and can be used to play in all keys.
