Selecting a scale
There are numerous classical compositions that were com-
posed using scales (or “temperaments”) that differ from the
“equal temperament” commonly used today. In order to re-
produce the original sound of such compositions, the C-720
provides other classical scales, in addition to the equal temper-
ament. In addition, scales to play ethnic and experimental mu-
sic are given.
You can assign the alternative temperament, or “sub scale”, to
both sounds, or just one of them. The other sound will contin-
ue playing using the equal temperament (or, in some cases, the
stretch one).

playing using the equal temperament.
5. Press SCROLL 

to select the L (Layer/Left) parameter:
6. Use the +/YES and -/NO button to turn the sub scale on or
off or the Layer/Left sound. If it is off, the sound will con-
tinue playing using the equal temperament.

Scale Meaning
Equal Temp. 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.
Pure Major Major chords in the selected key are perfectly
tuned.
Pure Minor Minor chords in the selected key are perfected
tuned.
Arabic An arabic scale, with the E and B notes tuned a
quarter tone lower.
Pythagorean Pythagorean scale, based on the music theo-
ries of the great Greek philosopher and mate-
matician. It is most suitable for melodies.
Werckmeister This is the Werckmeister III scale invented by
Andreas Werckmeister, the German organist
and music theoretician. This scale was created
in the later Baroque period to allow relatively
free transposition.

notes are slightly lower, while the highest
notes are slightly higher than the standard.
This scale is automatically recalled when select-
ing the GrandPiano, BriteGrand and MelloPi-
ano sounds.
