Harmonic Highlights

  • Employs a standard 12-bar minor blues structure in F minor, utilizing the Fm6 tonic to imply a melodic minor tonality.
  • Features heavy reliance on minor ii-V-i cadences (Gm7b5 โ€“ C7b9 โ€“ Fm6), emphasizing altered dominant tensions typical of the hard bop era.
  • The transition to the subdominant (Bbm7) is prepared via a secondary minor ii-V (Cm7b5 โ€“ F7b9), intensifying the harmonic drive toward the IV chord.
  • The turnaround maintains tension through repetitive ii-V cells, cycling back to the tonic with consistent voice-leading from the b13 of the V chord.

Improvisation Focus F Minor Blues scale integrated with F Melodic Minor to highlight the natural 6th and major 7th intervals over the tonic.

Difficulty Rating 2/5: The minor blues form is predictable and repetitive, though it requires fundamental knowledge of navigating minor ii-V-i cell structures.
