- The progression is driven by a repetitive $bII7$ to $im7$ movement (Db7 to Cm7), acting as a tritone substitution for the dominant V7 in C minor.
- It utilizes a modified minor blues structure that replaces traditional subdominant changes with a modal, Phrygian-influenced oscillation.
- The turnaround employs a chromatic dominant sequence (Eb7–D7b13–G7b9) to introduce altered tensions ($b13, b9$) before resolving to the tonic.
Improvisation Focus: C Minor Blues scale paired with the Db Lydian Dominant scale to navigate the $bII7$ chord.
Difficulty Rating: 2/5. The slow harmonic rhythm and repetitive nature are accessible, though soloists must understand tritone substitutions to address the Db7 accurately.
