Harmonic Highlights:
- Prominent use of Eb7#11 (IV7#11), immediately introducing a colorful Lydian Dominant sound.
- Frequent F9sus (V9sus) chord leading to Bb6, delaying tonic resolution and creating a modal, open feel.
- Extensive minor ii-V-i progressions (e.g., Dm7b5-G7b9-Cm7, Em7b5-A7b9-Cm7) which effectively tonicize the Cm7 (the ii chord of Bb).
Improvisation Focus: Targeting secondary ii-V-i progressions and altered dominant extensions.
Difficulty Rating: 4 (Advanced Intermediate). This standard demands fluent navigation of secondary dominant harmony and the application of various altered dominant scales.
