Harmonic Highlights:
- Predominant use of the I-vi-ii-V progression, firmly establishing C major as the key center.
- Features D7 (V/G) as a secondary dominant, introducing tension before resolving back to the tonic-related harmony.
- The Em7-A7 sequence provides a ii-V motion briefly targeting D, which then fluidly transitions into the Dm7 (ii of C) of the primary ii-V-I.
Improvisation Focus: Understanding ii-V-I chord-scale relationships.
Difficulty Rating: 3 (Intermediate). The progression features common jazz extensions, secondary dominants, and a brief temporary tonicization that require specific scale applications.
