Harmonic Analysis

This progression moves through F♯6 (Tonic) → G♯m (Supertonic) → C♯ (Dominant).

The I6–ii–V progression uses the major sixth chord as the tonic before moving into a ii–V turnaround. The warmth of the sixth chord establishes a relaxed home base, and the ii–V motion creates forward momentum that cycles the progression. This turnaround is a staple of jazz standards from the Great American Songbook era, where the sixth chord was the preferred tonic voicing.
