Harmonic Highlights:
- The foundational progression is a repeating ii-V-I in Eb major (Fm7-Bb7-Ebmaj7).
- A secondary dominant (C7, functioning as V7/ii) is consistently employed to initiate the next ii-V-I cycle.
- The entire phrase (Fm7-Bb7-Ebmaj7-C7) effectively demonstrates a cycle of fifths leading back to the ii chord.
Improvisation Focus: Navigating ii-V-I progressions and applying the Mixolydian scale over the dominant 7th chords (Bb7 and C7).
Difficulty Rating: 3/5. It requires a solid grasp of fundamental ii-V-I voicings and the use of secondary dominants, which are core jazz concepts.
