Harmonic Highlights:

  • Repeated Gm7-C7-Fmaj7 progressions strongly tonicize F major (IV), establishing it as a frequent temporary tonal center within the C major framework.
  • Features an abrupt, direct modulation from Fmaj7 to Amaj7, followed by a clear ii-V-I (Bm7-E7-Amaj7) progression, unexpectedly tonicizing A major (a major VI).
  • Employs common secondary dominant functions (e.g., D7 as V/G) and classic ii-V-I sequences (Dm7-G7) to navigate and return to the primary key.

Improvisation Focus: Navigating rapid key center shifts via advanced chord-scale application.

Difficulty Rating: 5 (Advanced). The frequent and often unexpected modulations, particularly the tonicization of Amaj7, demand a highly agile harmonic understanding and quick adaptability.
