- Features a ii-V-I to the IV chord (Fm7-Bb7-Ebmaj7), creating early harmonic motion away from the Bb tonic.
- Utilizes a “backdoor” ii-V sequence (Ebm7-Ab7#11) resolving to the tonic, replacing the traditional V7 with a bVII7 sound.
- Employs a cyclical chain of secondary dominants (G7-C7-F7) that creates a strong chromatic pull through the circle of fifths.
- Incorporates a distinctive Gbmaj7 to Gb7 shift, functioning as a non-diatonic color extension that emphasizes the flat-sixth degree.
Improvisation Focus
Targeting guide-tone transitions (3rds and 7ths) to navigate the descending dominant cycle.
Difficulty Rating
2/5: The progression follows predictable functional logic and moderate tempos, making it an ideal study for secondary dominant navigation.
