Harmonic Highlights

  • Establishes F major through recurring and predictable II-V-I progressions, providing a stable tonal center.
  • Employs chromatic dominant chords like Db7 (bII7/C or bVI7) resolving to V7 (C7), creating sophisticated tension and release.
  • Includes a clear temporary modulation to A minor (vi of F) via a iiø7-V7b9-i progression (Bm7b5-E7b9-Am7).
  • Features a bVII7 chord (Bb7) resolving to I (Fmaj7), adding a subtle bluesy or modal flavor.

Improvisation Focus Navigating chromatic dominant relationships and target chord tones over temporary modulations.

Difficulty Rating 3 (Intermediate) - While fundamental II-V-I movements are present, the inclusion of chromatic dominants, tritone substitutions, and temporary modulations demands a broader harmonic understanding.
