Harmonic Highlights

  • Prominent use of the non-diatonic Bb7 (IV7) creates a bluesy or dominant-substitute tension, moving away from a purely diatonic feel.
  • Classic I-VI-II-V (Fmaj7-Dm7-Gm7-C7) progressions serve as a core harmonic anchor, consistently resolving to the F major tonic.
  • The Em7-A7 progression functions as a II-V to D minor (vi), providing temporary harmonic movement and a common jazz turnaround element.

Improvisation Focus F Major Scale and its diatonic modes over individual chords.

Difficulty Rating 2 (Beginner-Intermediate). It utilizes standard II-V-I progressions and common non-diatonic chords, making it accessible for developing improvisers to practice fundamental jazz harmony.
