You can select various scales for the instrument. 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. This feature lets you experience the tunings of these genres.
Selecting a Scale
While holding down [FUNCTION], press one of the C5–F#5 keys. Holding down
both controls shows the current value on the display.
Selecting the Base Note
For scales 2 and 3 in particular, you should specify the key you intend to play (Base
Note). While holding down [FUNCTION], press one of the C4–B4 keys. Holding
down both controls shows the current value on the display.

Display Key Scale Description
1
C5 Equal
The pitch range of each octave is divided equally into twelve parts, with each half-step evenly spaced in
pitch. This is the most commonly used tuning in music today.
2
C#5 Pure Major
These tunings preserve the pure mathematical intervals of each scale, especially for triad chords (root,
third, fifth). You can hear this best in actual vocal harmonies—such as choirs and a cappella singing.
3
D5 Pure Minor
4
D#5 Pythagorean
This scale was devised by the famous Greek philosopher and is created from a series of perfect fifths,
which are collapsed into a single octave. The 3rd in this tuning are slightly unstable, but the 4th and 5th
are beautiful and suitable for some leads.
5
E5 Mean-Tone
This scale was created as an improvement on the Pythagorean scale, by making the major third interval
more “in tune.” It was especially popular from the 16th century to the 18th century. Handel, among oth-
ers, used this scale.
6
F5 Werckmeister
This composite scale combines the Werckmeister and Kirnberger systems, which were themselves
improvements on the mean-tone and Pythagorean scales. The main feature of this scale is that each
key has its own unique character. The scale was used extensively during the time of Bach and
Beethoven, and even now it is often used when performing period music on the harpsichord.
