Preset Scale Types
EQUAL The pitch range of each octave is divided equally into twelve parts, with
TEMPERAMENT each half-step evenly spaced in pitch. This is the most commonly used
tuning in music today.
PURE MAJOR These tunings preserve the pure mathematical intervals of each scale,
especially for triad chords (root, third, fifth). You can hear this best in
PURE MINOR
actual vocal harmonies – such as choirs and a cappella singing.
This scale was devised by the famous Greek philosopher and is created
PYTHAGOREAN
from a series of perfect fifths, which are collapsed into a single octave.
The 3rd in this tuning are slightly unstable, but the 4th and 5th are
beautiful and suitable for some leads.
MEAN-TONE This scale was created as an improvement on the Pythagorean scale, by
making the major third interval more "in tune." It was especially popu-
lar from the 16th century to the 18th century. Handel, among others,
used this scale.
WERCKMEISTER This composite scale combines the Werckmeister and Kirnberger sys-
tems, which were themselves improvements on the mean-tone and
KIRNBERGER
Pythagorean scales. The main feature of this scale is that each key has
its own unique character. The scale was used extensively during the
time of Bach and Beethoven, and even now it is often used when per-
forming period music on the harpsichord.
ARABIC Use these tunings when playing Arabic music.
