- Em7 to Cmaj7#11 (i - bVImaj7#11) introduces an early Lydian color, expanding the minor tonic’s harmonic vocabulary.
- A strong, extended temporary modulation to G minor (bIII) is established through sequential ii-V-i progressions (A7-D7-Gm, Cm-D7-Gm).
- Abrupt, non-functional chromatic side-slipping occurs with the Ebm/maj7 and Bbadd9/F chords, creating significant harmonic tension before resolving back to D7/F# leading to Gm7.
Improvisation Focus: Navigating rapidly shifting tonal centers, particularly between related minor keys and unexpected chromatic modulations.
Difficulty Rating: 5 (Advanced) - The frequent and distant modulations, coupled with complex chord qualities like bVImaj7#11 and Ebm/maj7, demand a sophisticated harmonic understanding and strong ear.
