The whole tone scale (WT) contains a total of six tones with the pattern T T T T T T. The whole tone scale is entirely made up from a series of tones and is therefore an other type of symmetrical scale mostly used over a dominant chord, e.g., the C WT fits over the C+7(#11). There are only two different keys for this scale and no modes as outlined here.
C WT: C D E F# G# Bb C or Db WT: Db Eb F G A B Db
All other keys and inversions are included in these two scales. For example the E whole tone scale has the same notes and is part of the C whole tone scale. The G whole tone has the same notes and is part of the Db whole tone scale, and so on.
The following example illustrates the C whole tone scale with the note pattern T T T T T T.
Example 313 is based upon the notes of the B whole tone scale.
Example 314 is a four bar progression in F minor utilising notes from various modes. The notes from the C whole tone scale appear in the third bar over a C+9 dominant chord.
Example 315 is a four bar progression in E major utilising notes from various modes in a riff style. The notes from the B whole tone scale appear in the fourth bar over a B+9(#11) dominant chord.
