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 cappella 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 tun-
ing 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.
The tuning of each note for the
currently selected scale is shown.
