Harmonic Highlights
- The pervasive Eb7 as a tonic chord immediately establishes a dominant-driven or blues-inflected harmonic character from the onset.
- A prominent cycle of secondary dominant 7ths (Gm7-C7-F7-Bb7) generates strong forward motion leading back to the Eb tonic.
- The A07 (A diminished 7th) introduces chromatic tension, likely functioning as a passing diminished or a Vii°7/V resolving towards the dominant.
- Standard ii-V-I progressions (Fm7-Bb7) provide fundamental jazz vocabulary for harmonic resolution.
Improvisation Focus Mixolydian modes for the numerous dominant 7th chords.
Difficulty Rating 3 (Intermediate). It features common jazz progressions like ii-V-I chains and secondary dominants, but the pervasive dominant 7th quality and a diminished chord add layers beyond basic diatonic playing.
