- The use of
Ab°7(bIII°7) functions as a chromatic passing chord between theImaj7andiim7, a hallmark of 1930s swing harmony that smooths the voice leading. - The bridge employs a classic modulation to the subdominant (
Bb6) initiated by a secondaryii-V(Cm7 - F7), providing a brief tonal shift typical of AABA structures. - Rapid chromatic dominant cycles (
Bb7 - A7 - Ab7) create descending parallel motion, providing strong leading-tone tension that resolves toward the tonic turnaround.
Improvisation Focus F Major Bebop Scale (integrating chromatic passing tones to align with the diminished harmony).
Difficulty Rating 2/5: The progression relies on standard diatonic cycles and predictable chromatic connectors, making it very accessible for intermediate players.
