You can select various scales.
Equal Temperament is the most common contempo-
rary 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 
the tunings of these genres.
See the procedure on page 72.
Setting range:
Equal One octave is divided into twelve equal inter-
vals. Currently most popular piano tuning 
scale.
PureMajor/PureMinor
Based on natural overtones, three major chords 
using these scales produce a beautiful, pure 
sound. They are sometimes used for chorus 
parts.
Pythagorean
This scale, designed by Pythagoras, a Greek 
philosopher, is composed of only five pitches. 
The 3rd produces swells, but the 4th and 5th 
are beautiful and suitable for some leads.
MeanTone
This scale is an improvement of the 
Pythagorean in that the swell of the 3rd has 
been eliminated. It spread during the late 16th 
century through the late 18th century. Handel 
used this scale.
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 also often 
used now to reproduce the music of that era on 
harpsichords.
Normal setting: 
Equal
If you select a scale other than Equal, you need to spec-
ify the root note using the B [–]/[+] buttons.
