- The progression centers on a recurring ii-I movement (Ebm7 to Dbmaj7) in Db Major, creating a relaxed, plagal-driven Bossa Nova feel despite the nominal Bb minor key.
- Inclusion of Eb9 alongside Ebm7 introduces a Mixolydian/Dorian ambiguity, adding a subtle blues-inflected tension to the subdominant function.
- The Bb7b5b9 acts as an altered secondary dominant (V/ii), providing a dark, chromatic pivot point to reset the phrase back to the Eb minor tonality.
- A shift from Fm9 to Ebmaj7 demonstrates a non-functional, downward step-wise modulation that breaks the established cycle, requiring a transition to Eb Ionian.
Improvisation Focus Db Major/Bb Natural Minor scales, with a specific focus on the Eb Dorian mode to capture the melancholic “saudade” character of the changes.
Difficulty Rating 3/5: While the tempo is generally slow, navigating the subtle shifts between dominant and minor qualities on the Eb chords requires precise modal targeting.
