Harmonic Highlights:
- The insistent Am7-Bm7b5 alternation firmly establishes the A minor tonality, highlighting the i-iiø7 progression.
- A classic Dm7-E7 (iv-V7) provides a strong dominant function, driving towards A minor.
- The Fmaj7 (bVImaj7) offers a characteristic modal color, a common substitute or passing chord in minor keys.
Improvisation Focus: A minor scales, fluidly transitioning between Aeolian/Dorian and Harmonic Minor elements.
Difficulty Rating: 3 (Intermediate). The mostly diatonic minor progression is accessible, but the constant iiø7 and the V7’s harmonic minor implications require careful navigation.
