Harmonic Highlights:
- Features prominent V7/V - V7 progressions (e.g., Bb7-Eb7) extending dominant harmony towards the tonic.
- Utilizes frequent ii-V-I progressions that resolve to both the tonic (Ab) and temporarily to the subdominant (Db).
- Incorporates a signature “backdoor” progression (Dbm7-Gb7-Abmaj7), providing a distinctive resolution to the tonic.
- Applies secondary dominants, such as F7 resolving to Bb7 (V7/ii), to create significant forward motion.
Improvisation Focus: Mixolydian mode, particularly its application over various dominant 7th chords.
Difficulty Rating: 3 (Intermediate). The rapid succession of functional harmony, secondary dominants, and the backdoor progression requires good harmonic recognition and navigation.
