Harmonic Highlights

  • Employs an expanded 24-bar minor blues structure, doubling the standard harmonic rhythm to create an elongated, spacious feel.
  • Utilizes a persistent $i7 - bII7$ (or $v7 - bVI7$) side-slipping motion, leveraging tritone substitutions to generate chromatic tension against the tonic.
  • Features $Gb7#11$ as a $subV$ approach to the $Fm6$ tonic, incorporating Lydian Dominant colors into the traditional minor blues turnaround.

Improvisation Focus F Melodic Minor, shifting to $Db$ Lydian Dominant to navigate the constant $#11$ tensions on the non-diatonic dominant chords.

Difficulty Rating 3/5. While the slow harmonic rhythm provides ample time, the player must accurately track the chromatic side-slipping and resolve non-diatonic extensions back to the $F$ minor center.
