- Repeated ii-V in C major: The opening
Dm7-G7sequences strongly imply a C major tonicization, further solidified by the arrival onC6. - Direct Modulation via Tritone Substitution: The
Ebm7-Ab7progression presents a clear ii-V in Db major, showcasing a chromatic half-step modulation or a tritone substitution for G7. - Flexible V7 function: The G7 chord functions variously as V7/iv in D minor and as the dominant in ii-V-I progressions resolving to C major.
- Minor ii-V: The
Em7-Am7phrase distinctly outlines a ii-V progression in the target key of D minor.
Improvisation Focus: Chord-scale theory application across changing tonal centers.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations and tritone substitutions require a strong understanding of navigating temporary key centers.
