Harmonic Highlights

  • Employs frequent ii-V-I progressions in F major (Gm7-C7-Fmaj7), often followed by a Bb7 (IV7) which adds a bluesy, subdominant flavor to the primary tonality.
  • Utilizes a minor ii-V-i (Em7b5-A7b9-Dm) to pivot temporarily to the relative minor, creating a sophisticated emotional shift within the A-B-A-C structure.
  • Incorporates secondary dominants such as D7#9 (V/ii) and G7 (V/V) to provide chromatic tension and reinforce resolutions back to the diatonic harmony.

Improvisation Focus Guide Tone Lines: Prioritize targeting the 3rds and 7ths of each chord to maintain melodic clarity through the frequent ii-V-I and secondary dominant cycles.

Difficulty Rating 2/5: The progression relies on foundational jazz movements and clear tonal centers, making it an excellent vehicle for beginners to practice standard vocabulary and voice leading.
