Harmonic Highlights

  • The progression utilizes sequential V-I resolutions descending chromatically (e.g., G7-Cmaj7 to F#7-Bmaj7), creating a sense of rapid, “cascading” tonality.
  • Extensive use of constant-structure Major 7th chords forces the harmony through distant centers like Db, C, B, and Bb, bypassing standard F minor diatonicism.
  • Dominant 7th “side-slipping” connects disparate keys via semitonal shifts, requiring smooth voice leading across non-functional transitions.
  1. Improvisation Focus Transposing melodic motifs through shifting Major/Lydian tonal centers.

  2. Difficulty Rating 4/5. The relentless chromatic modulations and non-diatonic root movements require high-level harmonic mapping and advanced mental agility.
