Harmonic Highlights

  • Employs a sophisticated 12-bar blues variation that utilizes “Monk-ish” chromaticism and frequent tritone substitutions (e.g., Eb7 to D7).
  • Features non-functional, parallel motion between dominant chords, specifically the descending sus-chord sequence (A7sus to Ab7sus) that delays the resolution to the G7 turnaround.
  • Utilizes “side-slipping” techniques where temporary tonal centers shift by half-steps, momentarily masking the C major key center.

Improvisation Focus C Mixolydian/Blues scale integrated with chromatic enclosure patterns and tritone-based melodic shapes.

Difficulty Rating 4 (Advanced) because the non-traditional blues structure and rapid chromatic shifts require high-level harmonic navigation and precise rhythmic phrasing.
