Harmonic Highlights:

  • Prevalent use of ii-V-I progressions in G major drives the harmonic rhythm, forming a core component.
  • Extended dominant chains (e.g., E7-Am7-D7) create strong forward motion leading towards the tonic or subdominant.
  • A sophisticated minor ii-V-i progression (C#m7b5-F#7b13-Bm7) temporarily tonicizes B minor, the iii chord of the overall key.
  • The F#7b13 chord demonstrates the use of altered dominant voicings to resolve to a minor tonic.

Improvisation Focus: Chord-scale theory for navigating diverse chord qualities and functional harmony.

Difficulty Rating: 3 (Intermediate) - While rooted in common ii-V-I movements, the presence of a distinct minor ii-V-i and extended dominant cycles requires a solid understanding of harmony beyond basic diatonicism.
