Chapter 3. Performance
Changing the Tuning
You can play classical styles such as Baroque using historic temperaments (tuning
methods).
Most modern songs are composed for and played in equal temperament, the most
common tuning in use today. But at one time, there were a wide variety of other
tuning systems in existence. By playing in the temperament that was in use when a
composition was created, you can experience the sonorities of chords originally
intended for that song.

Display Qualities
Equal
In this tuning, each octave is divided into twelve equal
steps. Every interval produces about the same amount of
slight dissonance.
Just(Maj)
This tuning eliminates ambiguities in the fifths and thirds.
It is unsuited to playing melodies and cannot be
transposed, but is capable of beautiful sonorities.
Just(min)
The Just tunings differ from major and minor keys. You
can get the same effect with the minor scale as with the
major scale.
Kirnberger
This is an improvement of the Mean Tone and Just tunings
that provides a high degree of freedom of modulation.
Performances are possible in all keys (III).
Pythagorean
This tuning, devised by the philosopher Pythagoras,
eliminates dissonance in fourths and fifths. Dissonance is
produced by third-interval chords, but melodies are
euphonious.
Mean Tone
This scale makes some compromises in just intonation,
enabling transposition to other keys.
You can save this setting in the
RG-7’s memory using the
Memory Backup function (p.
72).
