- The opening features a chromatic dominant descent (Bb7 - A7) resolving deceptively to Abmaj7, a signature Dameron harmonic surprise.
- Rapid shifts between secondary functions include D7 (tritone substitution for Ab7) resolving directly to Dbmaj7 (IV chord).
- Multiple descending chromatic ii-V sequences are prevalent, notably Dbm7-Gb7 (ii-V of Cb) to Cm7-F7 (ii-V of Bb), and Bm7-E7 (ii-V of A) to Bbm7-Eb7 (ii-V of Ab).
Improvisation Focus: Arpeggio outlining for precise navigation of the rapid, complex chord changes.
Difficulty Rating: 5 (Advanced). The sophisticated harmonic rhythm, frequent modulations, and advanced substitutions require extensive harmonic understanding.
