Harmonic Highlights

  • Extended sequence of dominant 7th chords (D9-G9-C7-Fmaj7) navigating through a cycle of fourths to reach the VI chord.
  • Sophisticated chromaticism featuring ii-V chains (B9-E9-A7) that delay resolution to the tonic A minor.
  • Sudden modulation in the bridge to E Major, using a ii-V-I (F#m7b5-B7-Emaj7) to create a high-contrast tonal shift.
  • Use of the G# diminished chord as a chromatic passing tone to bridge G7 and Am7, ensuring smooth stepwise bass motion.

Improvisation Focus Chromatic voice leading and the Altered Scale to navigate dense dominant-to-dominant transitions.

Difficulty Rating 4/5: The tuneโ€™s rapid modulations and non-diatonic dominant chains demand advanced harmonic awareness and precise guide-tone navigation.
