Scale Selection

To select a scale, click on the Scale pop-up and then

select the desired scale from the pop-up list.

Note: To avoid having to deal with scales containing those

annoying double flats, double sharps and notes like Cb, E#, Fb

and B#, Auto-Tune 3 will automatically choose the simpler of

two enharmonically equivalent scales. For example, if you select

Db Major, the Edit Scale Display will duly display the Db Major

scale. However, if you then go to the Scale selection pop-up and

select Minor, the Key will automatically be changed to C# and

the Edit Scale Display will, in fact, display the much friendlier C#

Minor scale. This will also be reflected on the Pitch Graph

Display in the Graphical Mode.

The Scales

Auto-Tune 3 comes with 29 preprogrammed scales. The first three scales

are equal tempered. These are the ubiquitous scales typically found in

Western tonal music. The other scales are historical, ethnic, and microtonal

scales. An in-depth discussion of these scales and their history is beyond

the scope of this manual. The interested reader will find more information

in Tuning In — Microtonality In Electronic Music by Scott R. Wilkinson,

published by Hal Leonard Books.

The following is a brief synopsis of the scales:

Modern equal temperament:

• major: a seven-tone equal tempered major scale.

• minor: a seven-tone equal tempered minor scale.

• Equal Tempered chrom.: a twelve-tone equal tempered chromatic scale.

Historical tunings:

• Ling Lun: a twelve-tone scale dating from 2700 B.C. China.

• Scholar’s Lute: a seven-tone scale dating from 300 B.C. China.

• Greek diatonic genus: a seven-tone scale from ancient Greece.

• Greek chromatic genus: a seven-tone scale from ancient Greece.

• Greek enharmonic genus: a seven-tone scale from ancient Greece.

• Pythagorean: a twelve-tone scale dating from 600 B.C. Greece. This

scale is derived by tuning twelve pure perfect fifths upward and adjust-

ing the octaves downward. This leads to some pure intervals and some

very impure intervals.
