  • The recurring Bb7 (IV7) chord within the F minor tonality creates a distinct bluesy dominant tension, often resolving back to Fm7 rather than acting as a V/Eb.
  • The sophisticated movement from Fm to Fm/maj7 (Fm(maj7)) to Fm7 adds rich chromatic voice leading and a melancholic color to the tonic chord.
  • A strong minor ii-V-i progression (Gm7b5 - C7alt - Fm) is effectively led by the Db7 (bVI7) chord, deeply reinforcing the minor key with functional harmony and altered dominants.

Improvisation Focus: F Harmonic Minor scale.

Difficulty Rating: 4 (Intermediate-Advanced). The blend of functional minor harmony, modal interchange, and altered dominant chords demands precise scale choices and harmonic awareness.
