- The opening Cm, Cm/maj7, Cm7, Cm6 progression establishes a sophisticated minor line cliché, utilizing chromatic ascent/descent of the 7th and 6th, often implying the melodic minor scale.
- Complex Diminished Chord Usage: F#07 functions as a V7b9 substitute (e.g., D7b9) leading to the iiø7 of F minor (Gm7b5), introducing an advanced altered dominant sound.
- Minor ii-V to Dominant ‘I’: The Gm7b5-C7b9 sequence creates a ii-V to F minor, but the resolution to Bbm6/Eb (functioning as an Eb13sus4) instead of a stable Fm tonic implies a continued dominant function or a temporary modulation.
Improvisation Focus: The Melodic Minor scale and its derived modes (especially Altered Dominant and Lydian Dominant) are crucial for navigating the minor line cliché and the various dominant and diminished chords.
Difficulty Rating: 4 (Advanced Intermediate) - The blend of minor line clichés, complex diminished chord substitutions, and ii-V resolutions to dominant ‘I’ chords requires a strong understanding of jazz harmony.
