- The progression utilizes a 16-bar structure built on parallel dominant 7th chords, moving primarily in whole steps (C7 to Bb7) to create a modal-blues hybrid.
- The harmonic rhythm deviates from standard blues by extending the durations of the I7 and bVII7 chords, delaying the arrival of the IV7 (Eb7) until measure nine.
- The final cadence features a rapid chromatic descent (D7-Db7-C7), requiring precise linear navigation through side-slipping dominant sonorities.
