Harmonic Highlights:
- The opening minor line cliché (Bbm, Bbm/maj7, Bbm7, Bbm6) establishes a rich, descending harmonic texture, setting a melancholic tone.
- A striking chromatic shift from Bbm to F#m7 creates immediate tension before resolving via Fm7 to a functional Bb13.
- Complex altered dominant voicings, such as Bb13, C7#9, and F7#9, are extensively used, generating strong forward motion and colorful dissonance.
- Frequent iiø7-V7 progressions (Cm7b5-F7) consistently reinforce the Bb minor tonic amidst intricate harmonic excursions.
Improvisation Focus: Melodic Minor modes, particularly Altered and Lydian Dominant scales.
Difficulty Rating: 4 (Advanced Intermediate). The rapid harmonic rhythm, chromatic substitutions, and advanced altered dominant voicings demand a sophisticated harmonic understanding.
