Select a root by pressing one of the keys in the
range shown in the illustration below. Remember
to keep the CONTROL button depressed.
• The note for the keyboard key you press is applied as
the root. If you press key F5, for example, the root
becomes F.
• No sound is produced when the keys are pressed.
• When Baroque Pitch (page E-29) is ON, the root is a
half-note higher than the key you press. This means
that to set a root of C, you should press B4.

About Temperaments
● Equal Temperament
This tuning system is the most widely used for keyboard
musical instruments in the world today. The octave is
divided into 12 semitones that are equal in frequency ratio.
With this system, you can perform in all the major and
minor keys without any adjustment. Though we take this
system for granted these days, it was a revolutionary
development in the history of music. Equal Temperament
tuning has been the most common system used in the
world since the middle of the 18th Century.
● Kirnberger III
This is also one of the precursors to equal temperament.
It is an evolution of just intonation and the mean-tone
system, and all keys (from C-major to F
-major) can be
used for keyboard play.
● Werckmeister
Werckmeister is a famous theorist who also did research
on equal temperament. This particular system is said to
be a precursor to equal temperament, and all keys (from
C-major to F
-major) can be used for keyboard play.
● Mean-Tone System
This system was the first actually used for tuning of
keyboard musical instruments. It was widely used starting
from the Renaissance up until the second half of the 18th
Century. During the days of Handel and Bach, it was
employed for cembalos, organs, and pianos.
● Pythagorean System
This system was developed by the philosopher
Pythagoras sometime during the 5th Century B.C. Most
of the fifths in this system do not deviate from the “pure”
(acoustically correct) intervals. The Pythagorean system
is perfect within a small range of tones and in the simple
keys, but it becomes inadequate in others. Despite this,
this system was used for Middle Age religious music,
which was performed (sung) using only the simple keys.
● Just Intonation
This system is one of the “pure” systems in which many
of the fifths and thirds are acoustically correct. Try setting
the root to C and playing C, E, G.
