Harmonic Highlights:

  • The initial Gmaj7 presents a parallel major context, immediately departing from the stated G minor tonic.
  • The harmony features sequential descending ii-V-I progressions, moving from F major (Gm7-C7-Fmaj7) to Eb major (Fm7-Bb7-Ebmaj7).
  • A subsequent Am7-D7 progression strongly establishes a ii-V leading to G major, further solidifying a major tonality for the “home” key area.

Improvisation Focus: Navigating ii-V-I progressions across multiple keys.

Difficulty Rating: 4. The frequent modulations via sequential ii-V-I progressions and the interplay between parallel major/minor make harmonic navigation challenging.
