1. Harmonic Progression Determines the shape of a composition.
A good harmonic progression has a purpose or goal.

2. Root Relationships ROOT not BASS Relationship to the key (tonality)
Ex: V sounds dominant
2) Relationship of interval between roots
Ex: I – IV is a 4th , ii – V is a 4th,
V – I is a 5th

3. Circle Progression Major: First two then skip across
Minor: First five then skip across

4. Circle Progression
Major: First two then skip across

5. Circle Progression
Minor: First five then skip across

6. Common Shortened
Circle Progressions

7. Circle Progressions occur with greater profusion near a cadence.

8. Half Cadence makes you expect tonic because it is a circle progression.

9. Other Progressions Backwards Circle - Ascending 5ths, Descending 4ths
Purpose is relief from motion towards tonic
Ascending Seconds -
Purpose is to switch from one circle progression to the next circle progression
Most common:
I – IV – V – I

11. Other Progressions Purpose is to move away from tonic.
Descending 3rds -
Purpose is to move away from tonic.

12. Dominant Function ChordsV
The real Slim Shady.
vii°
Dominant function, vii° I I6 4
Dominant function,  V  I I6 4

13. Repeated Chords =
No progression
