Owner's Manual
The pitch range of each octave is divided equally into twelve
parts, with each half-step evenly spaced in pitch. This is the most
commonly used tuning in music today.
These tunings preserve the pure mathematical intervals of each
scale, especially for triad chords (root, third, fifth). You can hear
this best in actual vocal harmonies—such as choirs and a cap-
pella singing.
This scale was devised by the famous Greek philosopher and is
created 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.
This scale was created as an improvement on the Pythagorean
scale, by making the major third interval more "in tune." It was
especially popular from the 16th century to the 18th century.
Handel, among others, used this scale.
This composite scale combines the Werckmeister and Kirn-
berger systems, which were themselves improvements on the
mean-tone and 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 performing
period music on the harpsichord.
Use these tunings when playing Arabic music.
