  • Standard diatonic ii-V-I progressions in F major form the primary harmonic movement throughout the tune.
  • The Am7b5 - D7b9 progression functions as a iiø7-V7/ii, leading to the Gm7 (ii chord) and introducing a temporary minor secondary dominant color.
  • A secondary dominant D7 (V7/ii) directly precedes Gm7, reinforcing the movement to the ii chord before resolving to the primary C7 (V7).

Improvisation Focus: Navigating ii-V progressions.

Difficulty Rating: 3 (Intermediate). The clear structure and repetitive ii-V movements are approachable, but secondary dominants require specific harmonic awareness.
