Harmonic Highlights:

  • Prominent use of an F pedal point in the opening, creating shifting chord qualities (Bbmaj7/F, Cm7/F, Dm7/F) over a static bass.
  • Frequent employment of ii-V-I progressions, notably Fm7-Bb7-Ebmaj7 and Em7b5-A7b9-Dm7, establishing temporary key centers or leading to dominants.
  • A striking C#m7-F#7-Cm7 sequence, functioning as a distant ii-V resolving to the iv chord of G minor, introducing significant chromaticism.

Improvisation Focus: Chord-scale application over evolving ii-V-I progressions and harmonic shifts.

Difficulty Rating: 4 (Advanced Intermediate). The blend of a pedal point, frequent modulations, and distant chromatic resolutions requires strong harmonic comprehension.
