- Functional diatonicism dominates the structure, primarily utilizing recurring ii-V7-I progressions (Am7 - D7 - Gmaj7) to establish the G major tonal center.
- The Bb°7 chord functions as a passing diminished chord (#i°7), creating chromatic voice leading into the ii chord (Am7).
- The progression maintains a traditional “rhythm changes” feel in its turnaround sections, alternating between tonic stability and dominant tension.
Improvisation Focus G Major Bebop Scale, emphasizing the transition between the 3rd and 7th guide tones during the frequent ii-V-I cycles.
Difficulty Rating 2/5 — The predictable harmonic rhythm and lack of modulation make it an accessible entry point for mastering basic swing phrasing and diatonic improvisation.
