Harmonic Highlights:
- Establishes a clear G major tonality with frequent diatonic I-ii-iii-ii progressions.
- Employs secondary dominants, such as G7 (V7/IV), to expand harmonic movement towards the subdominant.
- Features a bVII7 chord (F7) as a backdoor dominant, providing a blues-infused flavor before a common vi-V/V-V-I turnaround.
- Utilizes the standard jazz turnaround (Em7-A7-D7-G6) to reinforce the tonic at phrase endings.
Improvisation Focus: G Major scale and its diatonic modes (Dorian, Mixolydian) to effectively outline the specific chord changes.
Difficulty Rating: 3 (Intermediate). It combines foundational diatonic harmony with common jazz turnarounds and a distinctive backdoor dominant chord, requiring awareness of modal shifts.
