- Chromatic Dominant Descent: Employs a parallel sequence (G7–F♯7–F7–E7) to bridge the tonic area to the VI7 chord, utilizing smooth half-step voice leading.
- Circle of Fifths Resolution: Features a robust VI7–II7–V7–I (E7–A7–D7–G) turnaround, characteristic of early 20th-century swing and vaudeville structures.
- Tonic Prolongation: Incorporates diatonic substitutions like Em7 (vi) and G/D to maintain harmonic interest while remaining firmly anchored in the G Major key center.
Improvisation Focus G Major Blues Scale (blending the major 3rd and minor 3rd to navigate the shift between the tonic and the secondary dominant chords).
Difficulty Rating 2/5 — The predictable circle-of-fifths movement and repetitive 32-bar structure make it an accessible entry point for learning secondary dominants.
