Harmonic Highlights:
- The consistent opening employs a foundational I-vi-ii-V progression in C major, firmly establishing the tonic.
- A prominent
C7functions as a V7 of F, leading to the subdominant (F6) and initiating a temporary tonicization of F major. - The
Eb07chord serves as a chromatic passing diminished, creating tension before resolving to Dm7 (ii), adding sophisticated voice leading.
Improvisation Focus: Navigating ii-V-I progressions in both C and F major, with an emphasis on dominant 7th alterations and diminished chord targeting.
Difficulty Rating: 3/5. The mix of standard ii-V-I cycles with a chromatic diminished chord and subdominant tonicization requires intermediate harmonic understanding.
