Harmonic Highlights

  • The progression utilizes static modal blocks (F minor, Db Lydian Dominant, D Dorian) rather than functional V-I resolutions.
  • The shift from Db7#11 to Dm11 represents a chromatic parallel movement, transitioning from a bVI dominant structure to a natural vi minor.
  • Four-bar harmonic phrasing prioritizes groove and texture, utilizing quartal voicings (11ths) to create an “open” post-bop sound.

Improvisation Focus F Minor Pentatonic / Blues scale (provides a melodic “common thread” across all three chord changes).

Difficulty Rating 2/5: The slow harmonic rhythm allows ample time to navigate changes, and the entire structure can be simplified using a single blues scale.
