- The progression features a classic minor line cliché in the A section, moving from Cm7 through Cm7/Bb to Am7b5 and Abmaj7, creating a descending chromatic bass movement from the tonic to the submediant.
- It employs functional minor ii-V-I cells (Dm7b5 - G7b9 - Cm7) interleaved with secondary dominants like D7#9 (V/V), reinforcing the C minor tonality while adding bluesy tension.
- The structure incorporates a deceptive cadence feel when Am7b5 moves to Abmaj7, substituting the expected resolution with a major seventh chord on the flattened sixth degree.
Improvisation Focus C Minor Blues scale combined with C Melodic Minor to navigate the minor ii-V voice leading.
Difficulty Rating 3/5: The tune blends accessible blues vocabulary with sophisticated descending changes that require disciplined voice leading over minor ii-V-I sequences.
