<Equal Temperament>
This scale divides an octave into 12 equal parts using the
tuning system that is most widely used in Western
music.
<Pure Temperament (Tonic is C)>
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.
<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 XV-5080, you can use Arabian
temperament in the three keys of G, C and F.
