  • Harmonic Highlights

    • Extensive use of ii-V-I progressions, not just to the tonic (Gm7-C7-Fmaj7) but also to IV (Cm7-F7-Bbmaj7).
    • Frequent tonicization of diatonic chords like vi (Bm7b5-E7b9-Am7) and ii (Am7b5-D7b9-Gm7) through dedicated minor ii-V sequences.
    • The Bb07 chord provides a distinct chromatic embellishment, adding color and tension before further harmonic movement.
  • Improvisation Focus Targeting chord tones and outlining diverse ii-V progressions.

  • Difficulty Rating 3 (Intermediate). Requires solid comprehension of common ii-V progressions, secondary dominants, and navigating momentary tonicizations.
