Harmonic Highlights:

  • Dominant presence of the relative major (Fmaj7) frequently established by ii-V-I progressions (Gm7-C7-Fmaj7).
  • Effective use of the backdoor dominant (Eb7) often resolving to Fmaj7, sometimes prefaced by its minor ii (Bbm7-Eb7).
  • Incorporates secondary dominants like D7, functioning as V7/ii (leading to Gm7) in the F major context.
  • Features transient modulations, notably to Bb major via a ii-V-I progression (Cm7-F7-Bbmaj7).

Improvisation Focus: Chord tone outlining of ii-V-I progressions.

Difficulty Rating: 4 (Upper Intermediate). The frequent modulations, secondary dominants, and backdoor dominant resolutions demand quick harmonic adaptation.
