Harmonic Highlights

  • The progression utilizes frequent ii-V-I resolutions in F Major (Gm7-C7-F6), establishing the relative major before pivoting toward the D minor tonic.
  • A series of secondary dominant cycles (Am7-D7) creates a chain of V/ii chords, building harmonic tension that resolves into the G7 (V/V).
  • The transition from G7 to Gm7 represents a classic functional shift, moving from a secondary dominant to a predominant ii chord to restart the cadential cycle.
  • The final resolution employs a sharp minor ii-V-i (Em7b5-A7-Dm), requiring precise navigation of the A7 altered tensions to land on the D minor home key.

Improvisation Focus

Guide Tone Line Construction (focusing on 3rds and 7ths to navigate the rapid ii-V shifts).

Difficulty Rating

3/5: While the changes are functional, the performer must master the transition between the relative major and the minor ii-V-i turnaround.
