Harmonic Highlights:

  • Prominent use of the I-VI-II-V-I progression in F major (Fmaj7, Dm7, Gm7, C7), establishing a strong tonic foundation.
  • The Bbmaj7 (IV) chord functions as a subdominant extension, providing a brief harmonic anchor within the progression.
  • Sophisticated dominant preparation is observed in Dm7, G7sus, G7, C7, featuring a V/V (G7) enhanced by the G7sus, strongly leading to the tonic’s dominant.

Improvisation Focus: F Major scale and its diatonic modes, particularly Dorian and Mixolydian applied to ii-V progressions.

Difficulty Rating: 3 (Intermediate). The tune’s strong reliance on diatonic II-V-I progressions and standard secondary dominants makes it accessible, but the inclusion of sus chords and V/V requires attention to common jazz vocabulary.
