C7 - F7 - Bb7(V7/F - V7/Bb - V7/Eb), creating a strong harmonic pull back to the tonic. - Utilizes an additional extended dominant chain
G7 - C7 - F7(V7/C - V7/F - V7/Bb), indicating frequent temporary modulations and requiring agile harmonic navigation.

Difficulty Rating: 3 (Intermediate) - The frequent use of secondary dominant chains and passing diminished chords requires a solid grasp of functional harmony beyond basic diatonic progressions.
