Harmonic Highlights

  • The Am/maj7 chord provides a classic minor-major tonic sound, injecting inherent tension into the home key.
  • A clear Bm7b5 - E7b9 progression serves as a foundational minor iiø7-V7b9, firmly establishing the A minor tonality.
  • The G7sus - G7 sequence functions as a strong secondary dominant, preparing for a potential tonicization of the relative major, C.

Improvisation Focus The A Harmonic Minor scale is essential for navigating the minor-major tonic and the altered dominant V7b9.

Difficulty Rating 3 - Intermediate, due to the nuanced minor harmony including the minor-major tonic and altered dominant chords.
