  • Harmonic Highlights

    • Extensive use of dominant 7sus chords (I7sus, IV7sus, V7sus), creating an open, modal sound by delaying or avoiding traditional V-I functional resolutions.
    • Frequent IV7sus to I7sus (Bb7sus to F7sus) progression, establishing a characteristic plagal-like movement within the suspended dominant harmony.
    • Sudden chromatic shift with Dbmaj7#11, functioning as a striking non-diatonic color chord that momentarily disrupts the established F7sus pattern before returning.
  • Improvisation Focus Mixolydian scale, adapting for the Dbmaj7#11 via Db Lydian or Db Lydian Augmented.

  • Difficulty Rating 4 (Advanced). The static nature of the sus chords combined with the significant chromatic deviation of Dbmaj7#11 requires sophisticated melodic and harmonic navigation.
