Harmonic Highlights:

  • Features an iconic minor line cliché with a descending chromatic bass line over the Am tonic (Am7, Am/maj7/G#, Am/G).
  • Frequent deployment of altered dominant chords (A7b13, A7#9, Em7b5 A7#9, Ab7#11) introduces significant chromatic tension and color.
  • The tonic C major chord is consistently embellished with chromatic alterations (C, Caug, C6, C7), creating internal voice motion.
  • Ab7#11 functions as an advanced chromatic dominant, potentially a tritone substitution or a Lydian dominant, adding a sophisticated harmonic twist.

Improvisation Focus: Navigating altered dominant scales (Altered/Superlocrian) and their characteristic extensions over V7alt chords.

Difficulty Rating: 4 (Advanced Intermediate). The song’s reliance on altered dominant sonorities, a classic minor line cliché, and chromatic passing chords demands strong harmonic awareness and precise execution.
