Harmonic Highlights:
- Securely establishes G major through classic Imaj7-ii7-V7 progressions, often incorporating a G6 chord for melodic richness.
- Features a clear tonicization of C major via a Dm7-G7 (ii-V) leading directly to Cmaj7.
- The repeated Cø7 (C half-diminished) chords following Cmaj7/C6 introduce significant chromatic tension, signaling either a rapid, unusual modulation or an advanced reharmonization for expressive color.
Improvisation Focus: The major scale and its corresponding modes (Ionian, Mixolydian) across the primary and secondary tonal centers.
Difficulty Rating: 3 (Intermediate) - While the foundational ii-V-I movements are standard, the unexpected and unresolved Cø7 sequence demands specific harmonic awareness and navigation skills.
