Harmonic Highlights:

  • Frequent tonicization of the bIII major (Db major) via ii-V progressions (e.g., Ebm7-Ab7).
  • Prominent use of altered dominant chords (e.g., F7#5, A7#11) and tritone substitutions (e.g., G7 resolving to Dbmaj7) for harmonic color and unexpected resolutions.
  • Unconventional major chord movements, exploring chromatic mediant relationships such as Dbmaj7 (bIII) and Gbmaj7 (bVI).

Improvisation Focus: Emphasizing chord tones with chromatic embellishments to navigate the non-diatonic harmony.

Difficulty Rating: 4 (Advanced Intermediate). The frequent, non-diatonic modulations and altered chords require a sophisticated understanding of harmony and scale application.
