Harmonic Highlights:
- The juxtaposition of Dm7 (i), Em7 (ii natural), and the evocative Eb07 creates early modal color and harmonic friction outside a strict diatonic minor.
- Frequent V7b9 (A7b9) resolutions to Dm7 provide crucial anchors, re-establishing the tonic amidst temporary excursions.
- Sequential ii-V progressions (Fm7-Bb7, Gm7-C7) introduce temporary modulations to Eb major and F major, a hallmark of standard harmonic progression.
Improvisation Focus: Targeting chord tones and arpeggios across modulating ii-V sequences.
Difficulty Rating: 4 (Advanced Intermediate) Requires navigating frequent modulations and non-diatonic chords, demanding precise scale and arpeggio adjustments for improvisation.
