Harmonic Highlights:

  • Employs clear diatonic ii-V-I progressions (Dm7-G7-Cmaj7) as foundational elements.
  • Features recurring temporary tonicization of the vi minor chord (Am) through Bm7b5-E7b9 (ii-V to Am).
  • Utilizes a secondary dominant (D7) leading to the ii minor chord (Dm7), enhancing forward motion.
  • Includes a brief but distinct modulation or tonicization to the IV major (Fmaj7) via Gm7-C7.

Improvisation Focus: Navigating target chord tones and mode changes over the various ii-V-I sequences and temporary tonicizations.

Difficulty Rating: 3 (Intermediate) - Requires familiarity with standard ii-V-I resolution, secondary dominants, and navigating temporary key centers beyond the tonic.
