- The progression utilizes Ab7 (IV7) as a subdominant minor substitution, creating a “backdoor” chromatic resolution back to the tonic Ebmaj7.
- Secondary dominant chords like D7b13 are used to tonicize the iii chord (Gm7), adding harmonic tension and temporary shifts in tonal gravity.
- The sequence employs a classic iii-VI-ii-V turnaround (Gm7-C7-Fm7-Bb7) to create a cyclical, forward-moving motion typical of the Great American Songbook.
Improvisation Focus
The most critical concept is Guide Tone Leading, focusing on the smooth transition between the 3rds and 7ths of the ii-V-I and secondary dominant sequences.
Difficulty Rating
3 (Intermediate): While the harmonic rhythm is steady, the frequent use of secondary dominants and subdominant minor substitutions requires a clear understanding of functional voice leading.
