Harmonic Highlights

  • Frequent use of the minor ii-V-i turnaround (Bm7b5 - E7b13 - Am7) reinforces the A minor tonicity and provides a strong functional foundation.
  • The A7b9 chord acts as a secondary dominant (V7/iv), tonicizing the subdominant Dm7 to create melodic tension.
  • A brief modulation to the relative major occurs through a ii-V-I sequence (Dm7 - G7 - Cmaj7), offering a momentary shift in tonal color.
  • The inclusion of F7 serves as a bVI7 dominant, providing a sophisticated chromatic bridge back to the primary minor cadences.

Improvisation Focus A Minor Blues scale or A Melodic Minor.

Difficulty Rating 2/5: The slow harmonic rhythm and predictable cadences make it an ideal entry point for beginners to practice navigating minor key ii-V-I progressions.
