  • Harmonic Highlights

    • Establishes the F major tonic with a foundational ii-V-I progression.
    • Features a pronounced modulation to Ab major (the bIII of F) via an extended ii-V-I-IV progression (Cm7-F7-Bbm7-Eb7-Abmaj7).
    • Subsequently modulates to C major (the dominant of F) through a clear ii-V-I progression (Dm7-G7-Cmaj7).
    • Utilizes the Abm7 as an effective chromatic pre-dominant chord leading into the Gm7-C7 of F, adding harmonic color.
  • Improvisation Focus Navigating rapid, non-diatonic key center changes using appropriate scales and arpeggios.

  • Difficulty Rating 4 (Advanced). The rapid and unexpected modulations to Ab major and C major require a strong command of changing harmonic environments.
