Harmonic Highlights

  • The progression opens with a prolonged ii-V7 in F major (Gm7 - C7), delaying the resolution to the tonic C major by focusing on the subdominant (IV).
  • Structural use of minor ii-V-i sequences (Bm7b5 - E7 - Am7) reinforces the relative minor (vi), providing a melancholic contrast to the driving rhythm.
  • Secondary dominants (D7) and ii-V turnarounds (Am7b5 - D7) are utilized to pivot back to the Gm7, creating a continuous harmonic loop.

Improvisation Focus Navigating rapid ii-V-I cells across temporary key centers (F major and A minor) using Dorian and Mixolydian modes.

Difficulty Rating 3/5 — While the changes are diatonic, the fast tempo and frequent shifts between the IV chord and the relative minor require precise harmonic targeting and fluent voice leading.
