Harmonic Highlights:
- Prominent use of standard ii-V-I progressions resolving to the G major tonic.
- Frequent tonicization of the ii chord (Am7) through its own ii-V progression (Bm7b5 - E7b9), creating extended harmonic movement towards the supertonic.
- Dominant chords often incorporate altered extensions (e.g., E7b9), adding tension and a sophisticated harmonic color to the progressions.
Improvisation Focus: G Major Scale and its diatonic modes.
Difficulty Rating: 3 (Intermediate). The consistent application of secondary dominants and altered chords requires a solid understanding of functional harmony beyond basic diatonic playing.
