- Utilizes a classic iii-VI7-ii-V7 turnaround (Bm7-E7-Am7-D7), where the E7 acts as a secondary dominant to create a strong pull toward the supertonic (Am7).
- The bridge modulates to the subdominant (Cmaj7), immediately followed by an F9 (bVII7), which functions as a “backdoor” dominant to facilitate the return to the G major tonic.
- The progression relies on “Swing-era” functional harmony, alternating between static I-chord sections and active circle-of-fifths resolutions that define the AABA structure.
Improvisation Focus
G Major Bebop scale and guide-tone targeting (3rds and 7ths) to navigate the rapid ii-V turnarounds.
Difficulty Rating
2/5. The harmonic rhythm is brisk, but the progressions follow highly predictable, standard patterns common in early jazz repertoire.
