Harmonic Highlights:
- Prominent use of the IV7 chord (Eb7) within an Eb major context, imparting a bluesy character rather than strict diatonic function.
- Frequent V7 (Bb7) to IV7 (Eb7) movement, establishing a dominant-centric, blues-influenced harmonic rhythm.
- Incorporation of a ii-V-I progression (Cm7-F7-Bb7) in the dominant key (Bb major), which is V of Eb major.
- The G7 secondary dominant (V/Cm7) creates tension, resolving to the ii minor chord before the F7.
Improvisation Focus: Mixolydian mode and blues scales over the pervasive dominant 7th chords.
Difficulty Rating: 3 (Intermediate) – Requires navigating blues-infused dominant harmony and secondary dominant relationships within a moderately active progression.
