Harmonic Analysis

This progression moves through B♭ (Tonic) → Gm (Submediant) → Cm (Supertonic) → F (Dominant) → Dm (Mediant) → Gm (Submediant).

The I–vi–ii–V–iii–vi progression extends the standard turnaround with an additional iii–vi tail, creating a longer harmonic cycle that delays resolution. The circle-of-fifths motion continues past the expected cadence point, keeping the harmony in perpetual motion. This pattern appears in jazz ballads and sophisticated pop.
