Progression composition
Construction logic
Twelve-bar blues is built on degrees I, IV, and V. This page shows the condensed functional outline I – IV – I – V – IV – I without repeated bars. The chords are often voiced as dominant sevenths, whose minor sevenths create characteristic blues tension.
How it sounds
- Character
- Blues progression with dominant seventh chords
- Perceptual context
- Depends on melody, rhythm, tempo, register, and texture
- Stability
- High — resolves to tonic
- Completeness
- Ends on tonic function
Harmonic functions
Tonic establishes a stable centre, predominant prepares dominant, and dominant directs the motion back toward tonic.
Tensions & resolutions
Tension builds on V.
Harmonic context
Diatonic chords, scales, modes and cadences in the selected key:
The progression transposes to any key — the structure (degrees) stays the same, only the specific chords change.
Variability
- Replace triads with seventh chords for a richer sound
- Try chord inversions for smoother voice leading
- Add passing chords between the main degrees
