Harmonic Analysis

This progression moves through Cø7 (Supertonic) → F7 (Dominant) → Bbm (Tonic).

The iiø7–V7–i progression is the minor-key counterpart to the major ii–V7–I. The half-diminished chord on the second degree creates a dark, tense pre-dominant that moves to the dominant seventh before resolving to the minor tonic. This cadence is essential to minor-key jazz harmony and appears throughout the Great American Songbook whenever a tune modulates to or establishes a minor key.
