Harmonic Highlights

  • Uses a parallel minor descent (Fm6 - Ebm6 - Dbmaj7) that functions as a modal shift toward the submediant, creating a dark, Afro-Cuban atmosphere.
  • Employs standard minor ii-V-i cadences using altered dominants (C7#5) and tritone substitutions (Gb7) to resolve back to the tonic Fm6.
  • Features secondary dominant motion (D7#9) and non-functional chromaticism to bridge transitions between the A sections and the bridge.

Improvisation Focus F Melodic Minor scale (to emphasize the natural 6th on the Fm6 tonic and the major 7th on the V7alt chord).

Difficulty Rating 3/5: The parallel harmonic movement and altered dominant extensions require a solid understanding of minor key theory and Latin-to-swing rhythmic transitions.
