Harmonic Highlights:

  • The Fm - Fm(maj7) - Fm7 - Dm7b5 progression features a compelling chromatic bass descent under the minor tonic.
  • Sophisticated dominant chord usage, including chromatic movement (G7 - Gb7 - F7) and tritone substitution, adds harmonic tension.
  • Frequent temporary modulations to the relative major (Abmaj7) and bVII major (Ebmaj7) significantly expand the tonal landscape.

Improvisation Focus: F Harmonic Minor scale.

Difficulty Rating: 4 (Advanced Intermediate) - The intricate chromaticism, rapid modulations, and complex dominant chord movements demand precise melodic and harmonic navigation.
