- The progression utilizes frequent secondary dominants (G7, C7, D7) to create tension-resolution cycles leading to the ii (Cm7) and V (F7) chords.
- Transition to the subdominant (Ebmaj7) via a Bb7 (V7/IV) pivot establishes a brief tonal shift common in 32-bar AABA structures.
- The F7#5 provides chromatic voice-leading (C# to D) that strengthens the resolution back to the Bbmaj7 tonic.
- A passing diminished chord (E°7) facilitates a smooth chromatic ascent from the IV chord toward the dominant F7.
Improvisation Focus Guide Tone Navigation (targeting the 3rds and 7ths of the secondary dominants to outline the shifting harmonies).
Difficulty Rating 2/5: The harmonic rhythm is steady and the modulations are limited to closely related keys, making it an accessible entry point for practicing secondary dominant resolutions.
