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.
BAYAT/ RAST	Use these tunings when playing Arabic music.
PURE MAJOR	These tunings preserve the pure mathematical intervals of each scale,
PURE MINOR	especially for triad chords (root, third, fifth). You can hear this best in
	actual vocal harmonies – such as choirs and a cappella singing.
PYTHAGOREAN	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.
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-
KIRNBERGER	tems, 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 per-
	forming period music on the harpsichord.
