Playing the C-4500
7. Adjusting the pitch
You can make fine adjustments to the pitch.
This allows you to precisely match the pitch when
playing with other instruments.
The pitch can be adjusted in 0.5 Hz steps over a range
of 427.5–452.5 Hz (Hertz).
Raising the pitch
❍ Hold down the [TOUCH] switch, and press the
[PART 2] switch.
Each time you press the switch, the pitch will be
raised approximately 0.5 Hz.
+
Lowering the pitch
❍ Hold down the [TOUCH] switch, and press the
[PART 1] switch.
Each time you press the switch, the pitch will be
lowered approximately 0.5 Hz.
+
Restoring the original pitch
❍ Hold down the [TOUCH] switch, and simulta-
neously press the [PART 1] and [PART 2]
switches.
The pitch will return to the original setting
(A4=440 Hz)

The pitch setting you make is remembered even when the
power is turned off.
8. Selecting a temperament
There are numerous classical compositions that were
composed using temperaments that differ from the
“equal temperament” commonly used today.In order
to reproduce the original sound of such compositions,
the C-4500 provides Kirnberger and Werckmeister
classical temperaments, in addition to the equal
temperament widely used on keyboard instruments
today, allowing you to select from a total of three
temperaments.
Werckmeister
This is the Werckmeister III scale invented by Andreas
Werckmeister, the German organist and music theore-
tician. This scale was created in the later Baroque
period to allow relatively free transposition.
Kirnberger
This is the Kirnberger III scale invented by Johann
Phillip Kirnberger in the early 18th century, and is
used mainly for tuning harpsichords.
Equal temperament
Nearly all keyboard instruments today use equal
temperament. This temperament spaces all semitones
at equal distances, and allows identical scales to be
played in any key.
Changing the temperament
❍ Hold down the [TOUCH] switch, and press
either the [ORGAN] or [STRINGS] sound
selector switch to select the desired tempera-
ment.

Returning to equal temperament
❍ Hold down the [TOUCH] switch, and press the
[Sound selector] switch whose indicator is lit.
MeMO
When the power is turned on, equal temperament will be
selected automatically.
About stretched tuning
In order to produce the most natural resonance,
[PIANO 1] and [PIANO 2] use a “stretched tuning”
that makes the notes of the lower range slightly flatter
than equal temperament, and the upper range slightly
sharper.
