Harmonic Highlights

  • Rapid succession of ii-V progressions targeting multiple, distant key centers (e.g., F#m7-B7 to E, Abm7-Db7 to Gb, C#m7-F#7 to B), creating a highly chromatic landscape.
  • Extensive use of tritone substitutions and backdoor dominants (e.g., Fm7-Bb7, Bbm7-Eb7) to navigate through complex chord progressions and avoid direct resolutions.
  • Chromatic mediant relationships and unexpected major key changes, exemplified by the Dbmaj7 (bVImaj7) resolution, adding tension and harmonic color.

Improvisation Focus Targeting chord tones and extensions for each rapid chord change.

Difficulty Rating 5 (Advanced) - The tune demands sophisticated harmonic knowledge to navigate its fast-paced, chromatically shifting ii-V progressions and distant modulations.
