Harmonic Highlights:
- Standard ii-V-I progressions (Am7-D7-Gmaj7) form the primary harmonic motion throughout the key of G major.
- Frequent use of secondary dominants (e.g., Bm7-E7 leading to Am7, A7 leading to D7) expands the tonic area.
- The C7 chord functions as a backdoor dominant (bVII7) resolving to Gmaj7, adding a distinct harmonic color.
- A section features a descending cycle of fifths via V/iii-iii-V/V-V (B7b13-Em7-A7-D7), generating strong forward momentum.
Improvisation Focus: Targeting chord tones and guide tones over each changing harmony.
Difficulty Rating: 3 (Intermediate) Features common ii-V-I progressions and standard secondary dominants, requiring moderate harmonic awareness.
