Harmonic Highlights

  • Utilizes a sequence of descending Major ii-V-I progressions (targeting Fmaj7, Ebmaj7, and Dbmaj7) that move downward in whole steps.
  • Reimagines the traditional 12-bar blues structure by replacing standard dominant movements with sophisticated, modulatory major resolutions.
  • Employs a functional minor ii-V turnaround (Dm7b5 - G7b9) in the final two measures to resolve the harmonic tension back to the tonic C minor.
  1. Improvisation Focus Fluid navigation of rapid ii-V-I sequences using guide-tone voice leading.

  2. Difficulty Rating 3/5; the 12-bar form is accessible, but the constant modulation every two measures requires the improviser to switch key centers with high precision.
