- The A section utilizes an extended Bb7 pedal point, establishing a static dominant function that serves as a rhythmic and modal foundation for the Afro-Cuban “tumbao.”
- The bridge sequences through a cycle of fourths (Ab7 to Db7 to Gb7), transitioning the harmonic center from the Eb minor tonality toward the relative major.
- Chromatic ii-V-I patterns and tritone substitutions, such as D7b9 resolving to Gbmaj7, inject bebop-era tension into the otherwise repetitive Latin structure.
Improvisation Focus The Bb Altered scale (Bb, B, C#, D, E, F#, Ab) to bridge the gap between the static dominant vamp and the sophisticated harmonic shifts in the B section.
Difficulty Rating 3/5: The piece requires high rhythmic proficiency for the A section and the ability to navigate rapid, non-diatonic turnarounds in the bridge at a fast tempo.
