- The progression utilizes a diatonic ascent (IVmaj7 - v7 - vi7) that creates a pendulous, rolling motion over a subdominant foundation.
- The bridge executes a clear modulation to the relative minor (G minor) via repetitive V7 - i cadences using D7b9 to Gm7.
- Secondary dominants, specifically C7 (V/V), are employed to drive the harmonic motion toward the primary ii-V7 (Fm7-Bb7) in the home key of Bb major.
- The inclusion of the bVII (Ab) provides a brief subdominant minor flavor, adding a bluesy inflection to the otherwise diatonic structure.
Improvisation Focus Bb Major Pentatonic / Major Scale.
Difficulty Rating 2: The harmonic structure is predominantly diatonic with predictable modulations to the relative minor, making it very accessible for intermediate players.
