- The progression is anchored by a persistent I-vi-ii-V turnaround (C6-Am7-Dm7-G7), creating a cyclical harmonic motion typical of the pre-bebop era.
- Secondary dominants are utilized to heighten tension, specifically A7 acting as V/ii to resolve into Dm7 and D7 acting as V/V to resolve into G7.
- The sequence Em7-A7-Dm7-G7 represents a iii-VI-ii-V extension, which smoothly navigates the diatonic scale while providing more harmonic interest than a simple I-V.
- The rapid harmonic rhythm, often changing every two beats, necessitates concise voice leading within a stable C major tonality.
Improvisation Focus C Major Bebop scale and chord tone targeting to navigate the frequent I-vi-ii-V transitions.
Difficulty Rating 2/5: The harmony is highly predictable and remains strictly within the primary key, though the typically fast performance tempo requires technical agility.
