Using Other Tunings _
The RD-100 allows you to play classical music, such as
baroque with the tuning actually used in that period.
Most music today is composed and played based on the
assumption that Equal Temperament (the most com-
mon tuning method) will be used. However, various dif-
ferent tunings were in existence during the age of classi-
cal music. By playing a piece using such an “old” tuning,
you should be able to hear the natural sonorities of the
chords, and appreciate the piece in the way it was origi-
nally intended.
1 EQUAL: This tuning divides the octave equally into 12
intervals. All pitches have an equal, slight amount of
ambiguity.
2 PYTHAGOREAN: This method of tuning was invent-
ed by the famous philosopher Pythagoras. It resolves the
ambiguity of the fourths and fifths. The third, however,
is somewhat imperfect, but melodies sound clearer.
3 JUST (MAJOR): A method of tuning which resolved
the ambiguousness of fifths and thirds. Quite beautiful
sonorities are produced with chords, but the scale is
unbalanced, so it is not well-suited for melodies.
4 JUST (MINOR): With Just tuning, the tuning for
major is different from that for minor. The same effect as
the major version can be obtained with the minor one.
5 MEAN TONE: A temperament which adds some com-
promises to Just temperament, and facilitates transposi-
tion.
6 WERCKMEISTER: By combining the Mean Tone and
Pythagorean temperaments, it allows for playing in any
key.
7 KIRNBERGER: As a result of improvements made to
the Mean Tone and Just temperaments, it is relatively
tolerant towards transposition, and can be used to play
in all keys.
When you play using a tuning other than Equal Tem-
perament, you need to specify the root/fundamental
(“C” for major and “A” for minor) according to the key
of the song to be played. For ensemble playing with
other musical instruments, pitches will differ depending
on the key. Therefore, you should set the RD-100 to the
same basic pitch as the other instrument.
