- Utilizes the “Rhythm Changes” A-section framework, incorporating secondary dominants (III7-VI7-II7-V7) and frequent I-vi-ii-V turnarounds typical of the bebop idiom.
- The bridge features a signature descending chromatic sequence of ii-V cells (| Bm7 E7 | Bbm7 Eb7 | Am7 D7 | Abm7 Db7 |), diverging from the standard cycle-of-fourths bridge.
- Harmonic density is exceptionally high, with chord changes occurring every two beats in the bridge, necessitating rapid voice-leading across non-diatonic tonal centers.
Improvisation Focus Voice-leading through descending chromatic ii-V sequences.
Difficulty Rating 5/5: The bridge’s rapid chromatic modulations and the traditionally blistering tempo demand elite technical facility and advanced harmonic fluency.
