Harmonic Highlights:
- The prominent C7 chord functions as a V7/IV or bVII7, introducing early dominant or modal interchange coloration within the G major context.
- Frequent ii-V-I progressions, particularly Gm7-C7, establish temporary tonicizations to F major, exploring the subdominant’s key area.
- A distinct modulation to Bb major (bIII) is achieved through a clear Cm7-F7-Bbmaj7 ii-V-I, requiring adaptability to a distant tonal center.
Improvisation Focus: Adapting to temporary tonal centers and navigating altered dominant chord qualities.
Difficulty Rating: 4 (Advanced-Intermediate): The frequent modulations to distant keys and the use of altered dominants require a strong command of changing tonal centers.
