- V7-I7 Alternation: The A-section centers on a repetitive G7 to C7 movement, establishing a dominant-heavy blues tonality rather than a traditional diatonic tonic resolution.
- Chromatic Descending Resolution: Employs a ii-bII7-I7 (Dm7-Db7-C7) sequence, utilizing Db7 as a tritone substitute for G7 to create smooth semitone voice leading into the tonic.
- Passing Diminished Harmony: The Bb° acts as a chromatic bridge between the vi (Am7) and the tonic inversion (G6/B), facilitating a linear bass climb.
- Parallel Modal Shift: The bridge introduces Cm7 and Gm7, pivoting the key center from C major to the parallel C minor to deepen the harmonic tension.
Improvisation Focus C Mixolydian and C Blues scales to navigate the dominant-seventh-heavy A-sections.
Difficulty Rating 3/5 (Intermediate). While the slow tempo is accessible, the constant shift between major and minor tonalities and the use of tritone substitutions require precise harmonic awareness.
