Harmonic Highlights:
- Frequent and rapid modulations, particularly through major ii-V patterns (e.g., Em7-A7 to Dmaj, Bm7-E7b9 to Amaj), demanding quick key center adjustments.
- Strategic use of secondary dominants and tritone substitutions (Eb7, F7b9, Ab7) to create tension and unexpected resolutions outside of the G minor diatonic framework.
- Consistent emphasis on the relative major (Bbmaj7) provides a recurring point of melodic and harmonic arrival before further chromatic departures.
- The Ebm7-F7b9 sequence presents a minor ii-V of Bb, temporarily aligning with the parallel minor of the relative major.
Improvisation Focus: Arpeggio superimposition and chord-scale matching over rapidly shifting ii-V progressions.
Difficulty Rating: 4 (Advanced Intermediate) The frequent and non-diatonic modulations, including multiple ii-V cycles, require highly adaptable melodic and harmonic understanding.
