Adjusting the Standard
Pitch
Middle A is generally used as the standard reference
pitch for tuning instruments. When performing in
ensemble with other instruments, the ensemble will
not sound good if the instruments are not in tune with
each other. This tuning of all the instruments to a stan-
dard pitch is called Òmaster tuning.Ó

Selecting Tuning Curves

Pianos are commonly tuned so pitches in the lower
registers are adjusted relatively flat, and pitches in the
higher registers are tuned sharper compared to equal
temperament. This kind of tuning method for the
piano is called Òstretch tuning.Ó
The graphic representation of the differences in pitch
when comparing equal-tempered tuning with the
actual tuning used is called the Òtuning curve.Ó
Changing the tuning curve results in a subtle change
in the sound of the chords.
ÒONÓ is the power-on default for the tuning curve.
1. Press the [Function] button.
The [Function] buttonÕs indicator lights up.
2. Press the [Vibes] button.
3. Using the Value [+] and [-] buttons, change the
tuning curve.
