I am trying to understand how does notes relate to each other when writing a chord progression.
I understand that when composing on a Major scale chords acquire a function depending on the degree of the scale, these functions are as follows:
Functional Harmony Chord Functions
I ,iii, vi -> Tonic V , viiº -> Dominant IV, ii -> Sub Dominant * Uppercase = Major, Lowercase = Minor, º = diminished Example on C: C ,Em, Am -> Tonic G , Bº -> Dominant F, Dm -> Sub Dominant
Tonic Function Chords are those which contains the third degree of the scale which should define the overall sound of the scale.
Dominant Function Chord are those which contains the seventh degree on the scale, the seventh degree of the scale wants to go first degree of the scale, thus Dominant Function chords want to go to a Tonic Function Chord.
Sub Dominant Function Chords contain the fourth degree of the scale, which has no leading tone (seventh degree).
So as far as I know the progression tendency is as follows:
Dominant <-> Sub Dominant <-> Tonic
All that means is that chords are collections of scale degrees.
Each scale degree has its own tendencies. The collective tendencies of a chord’s scale degrees in combination is the chord’s function.
But how are this tendencies defined? I don't really understand why certain notes want to go move to certain notes of the scale, also how can I apply this on another scale, for example a minor scale or a major pentatonic scale.
Where can I learn about how notes tend to move in a chord progression?
Lastly, I want to assume that this is the way that chord progression charts work? - *Chord Progression Chart Example
How can I create a chord progression map for a scale?
