Harmonic Highlights

  • The initial Gm7b5 - C7b9 - Fm7 sequence establishes a movement to the relative minor from Abmaj7, utilizing a non-diatonic iiø7 chord (Gm7b5).
  • Features extensive, often chromatically descending, ii-V cycles, including Dbm7-Gb7, Cm7-F7, Bm7-E7, and the tonic Bbm7-Eb7.
  • Includes a prominent tonicization of the IV chord (Dbmaj7) via Em7 - Ebm7 - Ab7, showcasing chromatic minor chord movement leading to a V7-I resolution.

Improvisation Focus Navigating rapid, often distant, ii-V chord changes.

Difficulty Rating 4 (Advanced Intermediate) - The fast harmonic rhythm and frequent, complex tonicizations demand a strong grasp of altered scales and chord extensions.
