  • Harmonic Highlights

    • Frequent oscillation between F minor and F major tonalities, often via the Gm7-C7 (ii-V) progression resolving to F.
    • A prominent modulation to the bIII major key (Ab) is established with a clear Bbm7-Eb7-Ab (ii-V-I) progression.
    • Strategic use of diminished seventh chords (e.g., Ab07, B07, Db07) as passing tones, leading-tone functions, and dominant chord substitutions.
    • The B07 chord preceding Bbm7 in the Ab section functions as a tritone substitution for F7 (V7 of Bbm7), creating a chromatic approach.
  • Improvisation Focus Mastering F Harmonic Minor and Ab Major scales, emphasizing arpeggios for smooth navigation between tonic and bIII modulations.

  • Difficulty Rating 3 - Intermediate. Requires navigating frequent key center shifts between F minor and Ab major, alongside various diminished chord resolutions.
