Equal Temperament
This tuning divides the octave into 12 equal parts, and is the most
widely used method of temperament used in Western music. The
JUNO-G employs equal temperament when the Scale Tune Switch
is set to “OFF.”
Just Temperament (Tonic of C)
Compared with equal temperament, the principle triads sound
pure in this tuning. However, this effect is achieved only in one
key, and the triads will become ambiguous if you transpose.
Arabian Scale
In this scale, E and B are a quarter note lower and C#, F# and G#
are a quarter-note higher compared to equal temperament. The
intervals between G and B, C and E, F and G#, Bb and C#, and Eb
and F# have a natural third-the interval between a major third and
a minor third. On the JUNO-G, you can use Arabian temperament
in the three keys of G, C and F.
