Harmonic Highlights:
- Frequent use of ii-V-I progressions (Fm7-Bb7-Ebmaj7) firmly establishing the key center.
- Regular application of secondary dominants, notably C7b9 functioning as V/Fm.
- Prominent inclusion of the “backdoor” dominant (Ab7) resolving to Ebmaj7, adding a characteristic jazz sound.
- Blues-infused dominant harmony on the tonic (Eb7) and subdominant (Ab7, Db7) adds a distinct bluesy character and chromatic movement.
Improvisation Focus: Mixolydian scales for dominant chords, integrated with the Eb major scale.
Difficulty Rating: 3 (Intermediate). It presents standard ii-V-I progressions and secondary dominants alongside more complex blues-infused harmonies and chromatic shifts.
