Harmonic Highlights:
- The bVIImaj7 chord (Gmaj7) functions prominently as a structural element, often initiating or concluding sections, hinting at a broader tonal palette than pure A minor.
- Standard ii-V-i progressions clearly establish tonicizations in A minor (Bm7 E7 Am7) and feature a significant modulation to E minor (F#m7b5 B7b13 Em7).
- The progression incorporates a backdoor ii-V (Cm7 F7) and a secondary ii-V (Am7 D7) to G, adding harmonic color and driving motion through non-diatonic pathways.
Improvisation Focus: Chord tones and arpeggios.
Difficulty Rating: 4 - Frequent modulations, secondary dominants, and non-diatonic chords demand strong chord-scale knowledge and adaptability.
