  • Classic iim7b5-V7b9-i cadence (Gm7b5-C7b9-Fm) firmly establishes the F minor key center.
  • Frequent and strong ii-V-I progressions (Bbm7-Eb7-Abmaj7) clearly tonicize the relative major, Ab major.
  • The progression alternates effectively between the F minor tonic and extended sections affirming Ab major, creating a sense of dramatic contrast.
  • Eb7b9 acts as a strong V7 leading back to Abmaj7, reinforcing the relative major tonality.

Improvisation Focus: Navigating the F harmonic minor scale over V7 chords and the Ab major scale for relative major sections.

Difficulty Rating: 3 (Intermediate). Requires comfortable command of minor ii-V-i progressions and smooth navigation between relative minor and major key areas.
