Harmonic Highlights:

  • Extensive use of descending dominant 7th cycles (e.g., F#7-Bmaj7, A7-Dmaj7) facilitating rapid modulations to distant key centers.
  • Frequent tritone substitutions (e.g., G7 resolving to Cmaj7, Ab7 leading to Dbmaj7) that obscure traditional functional harmony.
  • Passages featuring chromatic major seventh chords (Dbmaj7-Bmaj7-Amaj7) introduce striking non-diatonic colors and voice leading.
  • Temporary ii-V-I progressions in remote keys (e.g., Fm7-Bb7-Ebmaj7) further destabilize the F minor tonal center.

Improvisation Focus: Chord-scale theory with an emphasis on altered dominant scales and navigating rapid key changes.

Difficulty Rating: 5 (Advanced) Its rapid, non-diatonic modulations and extensive use of altered dominants require sophisticated chord-scale knowledge and harmonic agility.
