Harmonic Highlights:

  • Features a chromatic diminished chord pair (G07, Gb07) creating tension and unexpected passing motion.
  • Includes a clear, temporary modulation to the relative major (Dbmaj7 section via Gbmaj7-Db/F-Ebm7-Dbmaj7).
  • Frequent V/V-V cycles (C7b9-F7b9) strongly resolve to the tonic or new temporary key centers.
  • Incorporates major-mode tonicization (Cm7-F7 leading to Bb major) within the overall Bb minor context, creating harmonic ambiguity.

Improvisation Focus: Navigating rapid harmonic rhythm and targeting chord tones through various temporary key centers.

Difficulty Rating: 5 (Advanced) Rapid harmonic rhythm, complex dominant and diminished chord voicings, and frequent modulations demand a sophisticated understanding of functional harmony and improvisation techniques.
