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.

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).

 

 

 

 

 

 

 

 

 

 

 

 

This tuning, devised by the philosopher Pythagoras,

 

 

Pythagorean

 

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).
