- A foundational twelve-bar blues form in Eb major underpins the composition (Eb7, Ab7, Bb7).
- Extensive integration of ii-V progressions, notably Cm7-F7 (to Bb) and Gm7b5-C7b5b9 (implying F minor or altered dominant function).
- Frequent deployment of altered dominant chords (C7b5b9, Bb7b5) introduces significant chromatic tension and modern harmonic color.
Improvisation Focus: Mixolydian mode, especially its altered variants, to navigate the frequent dominant 7th and altered dominant chords.
Difficulty Rating: 5 (Advanced). The blend of a blues structure with complex bebop ii-V changes and specific altered dominant voicings demands sophisticated harmonic understanding and execution.
