Harmonic Highlights:

  • Frequent establishment of Eb major (Fm7 Bb7 Ebmaj7), the relative major of C minor, as a primary harmonic center.
  • Strong modulation to G major (Am7 D7 G6/Gmaj7), the dominant of C minor, providing a distinct contrasting section.
  • Brief pivot to G minor (Gm F#07) within the dominant area, adding modal color before returning to the relative major.
  • The use of altered dominants, like D7#5, indicates sophisticated voice leading and tension-building opportunities.

Improvisation Focus: Navigating II-V-I changes across multiple, transient key centers (Eb major, G major).

Difficulty Rating: 4 (Advanced Intermediate) - The rapid modulations to secondary key centers and inclusion of altered dominant chords demand agile harmonic recognition and scale application.
