Harmonic Highlights:

  • The opening Gm7b5 - C7b9 - Fmaj7 progression introduces a sophisticated ‘minor iiø-V7b9’ tension resolving to a major tonic, adding a blues-inflected color.
  • Features a standard diatonic Gm7 - C7 - Fmaj7 (ii-V-I) progression, providing a foundational contrast to earlier altered harmonies.
  • Includes a prominent modulation to Amaj7 via a Bm7 - E7 (ii-V) progression, moving up a major third from the home key of F.
  • The interplay between altered and diatonic ii-V progressions demands quick harmonic adaptation.

Improvisation Focus: Chord Tones and Arpeggios, vital for navigating altered dominants and temporary modulations.

Difficulty Rating: 4 (Advanced Intermediate) The specific altered chords (Gm7b5, C7b9) and the significant modulation to Amaj7 require precise harmonic awareness and quick adaptation.
