- Frequent use of V7/IV (Ab7) to target the subdominant (Db), creating a blues-inflected swing feel typical of the Ellington-Strayhorn era.
- Chromatic passing motion via the D°7 (#IV°7) between the IV and the tonic over its fifth (Ab/Eb), facilitating smooth linear bass movement.
- Strong reliance on ii-V-I cadences (Bbm7-Eb7-Ab6) to reinforce the Ab major tonal center amidst stepwise diatonic motion.
- Sophisticated use of inversions, such as Ab7/C and Ab/C, to create a walking bass line within the piano/orchestral voicing.
Improvisation Focus The Ab Major Bebop scale, with specific attention to the #4 (D natural) to bridge the gap between the IV chord and the tonic.
Difficulty Rating 2/5. The predictable diatonic structure and moderate swing tempo make it an accessible study in basic chromatic voice leading and standard jazz turnarounds.
