- The progression utilizes a secondary dominant G7 ($V^7/IV$) to tonicize the IV chord (C), creating a bridge toward the subdominant area.
- A classic IV-iv modal interchange (C to Cm) introduces the $\flat6$ degree (Eb), providing a poignant chromatic voice-leading path back to the tonic.
- The inclusion of E7 ($VI^7$) serves as a secondary dominant to the ii chord (Am7), establishing a standard circle-of-fifths motion common in swing-era harmony.
- Structural stability is maintained through repetitive ii-V-I turnarounds (Am7-D7-G), reinforcing the G major tonality throughout the form.
Improvisation Focus G Major Scale with specific chord-tone targeting of the Eb (b3 of Cm) to outline the minor subdominant coloration.
Difficulty Rating 2/5 — The tune follows predictable diatonic patterns and standard secondary dominants, making it highly accessible for intermediate improvisers.
