- Features a rapid modulation to the bIII key area (Ab major) via a ii-V sequence (Bbm7-Eb7), a hallmark of sophisticated swing-era compositions.
- Employs the #iv diminished chord (B°7) as a chromatic connector between the subdominant (Bbmaj7) and the tonic (Fmaj7/C).
- Utilizes secondary dominants (D7 and D7b9) to create a strong pull toward the ii chord (Gm7), reinforcing the home key.
- The structure relies on recurring ii-V-I turnarounds in F major to anchor the harmony amidst temporary modulations.
Improvisation Focus
Voice leading through the ii-V-I sequences, specifically targeting the shift from the F major tonic to the temporary Ab major tonal center.
Difficulty Rating
3/5: The progression is largely diatonic to F major but requires fluid navigation of the quick shift to Ab major and back.
