Harmonic Highlights:
- The G#07 (vii°7) provides a clear leading-tone function, firmly establishing A minor as the tonic.
- A recurring Am7-D7 progression functions as i - V/bVII, creating an extended dominant pull towards G without full resolution.
- Descending chromatic bass lines (Em-Em/D-Em/C#) add intricate internal motion and color to the v chord.
- Strategic use of secondary dominants (B7 for Em, A7 for Dm) and a bIII7 (C7) enriches the minor tonality with colorful tension.
Improvisation Focus: A Dorian mode.
Difficulty Rating: 4 (Advanced Intermediate). Frequent and varied secondary dominant functions and recurring V/bVII progressions demand sophisticated chord-scale application.
