Harmonic Highlights:

  • The opening Gmaj7 - C7#11 creates a distinctive recurring motif, where the C7#11 functions as a colorful, non-diatonic Lydian dominant.
  • A chromatic minor progression (C#m7b5 - Cm6) introduces temporary harmonic ambiguity and movement away from the G major tonality.
  • A robust cycle of secondary and altered dominants (G6/B - E7#5 - A7 - D7) drives towards the tonic, featuring a strong #5 alteration on the E7.

Improvisation Focus: Altered dominant scales.

Difficulty Rating: 3 (Intermediate). Its use of non-diatonic dominants, chromatic voice leading, and altered chords requires a solid understanding of jazz harmony beyond basic diatonicism.
