This scale divides an octave into 12 equal parts using the
tuning system that is most widely used in Western
music.
With this tuning, the three fundamental chords sound
richer compared to equal temperament. This effect only
applies to one key, and transposition can produce less-
pleasing results.
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 XV-5080, you can use Arabian
temperament in the three keys of G, C and F.
