- Utilization of the #IĀ°7 passing diminished chord (EĀ°7) to create chromatic voice-leading between the tonic (Ebmaj7) and the supertonic (Fm7).
- Extensive secondary dominant chains (VI7 - II7 - V7), specifically C7 to F7 to Bb7, providing a strong directional pull back to the Eb tonic.
- Frequent III7 - VI7 (G7 - C7) motion, which briefly tonicizes the submediant and adds a characteristic early-jazz “stride” harmonic complexity.
Improvisation Focus Chord Tone Arpeggiation, specifically targeting the 3rd and 7th of the secondary dominants to navigate the rapid circle-of-fifths movement.
Difficulty Rating 2/5: The progression follows predictable functional harmony and standard swing-era turnarounds, making it highly accessible for intermediate improvisers.
