112. THE HARMONIC STATISTICAL PROFILE OF A CHORD PROGRESSION

(This post has not being written completely yet)

This post describes that the harmonic statistical profile of melodies as in post  , applies also to chord progressions, and in this way it is explained why the suggest chord-cycles or chord-wheels or chord-scales as paragraph 89, are the suggested order.

In the statistics, we may study the shapes of melodic themes bu the polarity of them (similar to the polarity of chords as Power-chords=neutral major chords=positive minor or more exotic chords=negative).


The 3 polarities +, - 0 of a melodic theme, and the 3 basic shapes of them: Expansion, Contraction and Cycles. Ascending, Descending Stationary. 

The 3 polarities + , -, 0 , are the correspondent to the melodic themes that the chord types major, minor and power chord are for harmonic triads.

The 3  basic shapes of them: Expansion, Contraction and Cycles, are the correspondent to the melodic themes that the chord extension  types like with 4th, with 6th with 7nth  are for harmonic triads.
