Harmonic Highlights:
- Prominent use of Eb7 (bIII7) functioning as a chromatic dominant or substitute, often leading into the IIm7-V7 progression.
- Incorporation of C7 (V7/IV) resolving to Fmaj7 (IVmaj7), a common secondary dominant.
- The Bb7 (bVII7) frequently appears, acting as a backdoor dominant or preceding a IIIm7-VI7-IIm7-V7 turnaround.
- Frequent use of the IIIm7-VI7-IIm7-V7 (Em7-A7-Dm7-G7) turnaround provides consistent harmonic motion.
Improvisation Focus: Navigating altered Mixolydian scales and chromatic dominant substitutions.
Difficulty Rating: 3 (Intermediate). The primary challenge lies in executing the non-diatonic Eb7 and Bb7 chords smoothly within the otherwise conventional progressions.
