- Frequent use of ii-V-I cadences in Bb major (Cm7-F7-Bbmaj7) interspersed with secondary dominants (G7 to Cm7, D7 to Gm7) to drive harmonic momentum.
- Brief tonicization of the IV chord (Eb6) via a ii-V of IV (Fm7-Bb7), a hallmark of the Nestico/Basie swing style.
- Strategic placement of chromatic passing diminished chords (Db°7) to facilitate smooth stepwise bass motion between the ii and V chords.
- Utilization of extended and altered dominant colors (C9, F7b9) to provide sophisticated tension-release patterns within a traditional blues-inflected framework.
Improvisation Focus Voice leading through secondary dominants using guide tones (3rds and 7ths) to clearly outline functional shifts.
Difficulty Rating 3/5: While the key center is stable, the frequent secondary dominants and chromatic passing chords require a fluid command of ii-V-I patterns and precise harmonic navigation.
