- Employs an extended sequence of secondary dominants (III7–VI7–II7–V7) that drives the harmony through the circle of fourths back to the tonic Bb.
- Utilizes chromatic passing diminished chords (Db°7) to create smooth voice-leading between the I chord and the ii-V7 turnaround.
- Features a brief modulation to the key of D major via a ii-V-I (Dm7–A7–D) sequence, momentarily departing from the Bb major tonal center.
- Relies on “Ragtime” harmonic logic where dominant 7th chords act as primary structural pillars rather than just functional resolutions.
Improvisation Focus Arpeggiating the secondary dominant cycle (D7-G7-C7-F7) to highlight chromatic guide-tone resolutions.
Difficulty Rating 2/5: The progression follows a predictable circle-of-fifths logic, making it accessible despite the typically fast “Stride” tempo.
