Harmonic Highlights

  • Features a systematic minor-third cycle (Bbm7-Dbm7-Em7-Gm7) that bypasses traditional functional harmony through symmetrical movement.
  • Utilizes “Constant Structure” minor 7th chords, requiring the soloist to shift identical modal shapes across non-diatonic root movements.
  • Integrates brief, compressed ii-V patterns (like Cm7-D7#9-Gm7) to provide momentary resolution within the otherwise “floating” modal framework.
  • Implements a “cyclic” design where the harmony traverses the diminished axis before returning to the starting point.

Improvisation Focus Dorian mode transposition and pattern-based cell shifting.

Difficulty Rating 4/5: The combination of rapid tempos and non-functional, symmetrical chord changes demands advanced mental mapping and technical fluidity.
