FR-7x V-Accordion
Scale (Tuning)
Almost every music culture has its own accordion vari-
ety. Arabic, Indonesian and other musical cultures do
not use the equal temperament that is favored in
Europe, the Americas, etc.
The FR-7x features a “Scale” parameter that allows you
to select the tuning system that best fits the music you
want to play. If the tuning system you need is not
among the factory settings, you can program it yourself
(see “1.4 Scale Edit” on p. 64), save it to a User1~3 mem-
ory and then select it here.
(1) While the main page is displayed, press the [UP]
button three times.
(2) Rotate the [DATA÷ENTER] knob to select the a dif-
ferent tuning system.
The possibilities are:
Except for “Equal”, you also need to specify the root/
fundamental (“C” for major and “A” for minor)
according to the key of the song to be played.
(3) Press the [DATA÷ENTER] knob to activate the “KEY”
field (so that it is displayed in reverse).
(4) Turn the [DATA÷ENTER] knob to select the desired
root note (C~B).
(5) Press [EXIT÷JUMP] to return to the main page.
Scale Description
Equal (Off) This tuning divides each octave into 12
equal steps (intervals).
User 1~3 These settings refer to the tuning systems
programmed by yourself (or someone
else). See “1.4 Scale Edit” on p. 64 for
details.
Arabic 1 & 2 These two settings refer to Arabic tuning
systems. Select “1” to lower the E and B
notes by a quarter tone (–50 cents).
“2” represents a scale where the E and A
are tuned down a quarter tone.
Just Major This is a classical (western) tuning that
resolved the ambiguity of fifths and
thirds. Quite beautiful sonorities are pro-
duced with chords, but the scale is unbal-
anced, so it is not well-suited for melodies.
Just Minor This is a just scale for pieces in minor keys.
Pythagorean This system was invented in ancient
Greece. It resolves the ambiguity of
fourths and fifths. Though thirds are
somewhat imperfect, melodies sound
clearer.
Mean-Tone A temperament that adds some compro-
mises to the just temperament and facili-
tates transposition.

Werckmeister A combination of the Mean Tone and
Pythagorean temperaments, this tuning
allows for playing in any key.
Kirnberger As a result of improvements made to the
Mean Tone and Just temperaments, this
tuning system is relatively tolerant
towards transposition and can be used to
play in all keys.
