Harmonic Highlights:
- Prominent iiø7 - V7 - i (Am7b5 - D7 - Gm7) establishes the foundational minor key movement.
- The Eb7 - D7 progression introduces a characteristic Spanish Phrygian or bluesy dominant sound, moving from bVI7 to V7 without a standard diatonic resolution.
- F7 - Bbmaj7 functions as a brief tonicization to the relative major (Bb), temporarily shifting the harmonic focus within the minor key.
Improvisation Focus: G Harmonic Minor scale, especially over the D7 and Gm7 chords, to emphasize the minor tonality.
Difficulty Rating: 3 (Intermediate) - The core ii-V-i is standard, but the non-diatonic Eb7-D7 movement and temporary relative major modulation require specific scale choices and harmonic awareness.
