TERMINOLOGY
Hz (Hertz):
This unit of measurement refers to the frequency of a sound and
represents the number of times a sound wave vibrates in a second.

F2. Selecting a Scale

You can select various scales.
Equal Temperament is the most common
contemporary piano tuning scale. However,
history has known numerous other scales,
many of which serve as the basis for certain
genres of music. You can experience these
tunings with the instrument.
Equal Temperament
One octave is divided into twelve equal intervals.
Currently the most popular piano tuning scale.
Pure Major/Pure Minor
Based on natural overtones, three major chords using
these scales produce a beautiful, pure sound.
Pythagorean
This scale, designed by Pythagoras, a Greek philosopher,
is based on the interval of a perfect 5th.
.
Setting range:
427.0 – 453.0 (Hz)
Normal setting:
440.0 (Hz)
The 3rd produces swells, but the 4th and 5th are beauti-
ful and suitable for some leads.
Mean Tone
This scale is an improvement of the Pythagorean in that
the swell of the 3rd has been eliminated. The scale
became popular during the late 16th century through the
late 18th century, and was used by Handel.
Werckmeister/Kirnberger
These scales combine Mean Tone and Pythagorean in
different ways. With these scales, modulation changes the
impression and feel of the songs. They were often used in
the era of Bach and Beethoven. They are often used today
to reproduce the music of that era on harpsichords.
