- Employs a standard 12-bar blues structure in Bb, emphasizing the I-IV-V relationship with jazz-influenced extensions.
- Incorporates a chromatic ascending passing chord (C#dim7) between the ii (Cm7) and the I over the third (Bb/D) during the turnaround.
- Features a VI-ii-V-I progression (G7#9 to Cm7 to F7) which utilizes a secondary dominant to create stronger directional pull toward the resolution.
- Utilizes a “backdoor” chromatic movement (Gb7/E) near the final cadence to add harmonic tension before resolving to the dominant F7.
Improvisation Focus The Bb Major Pentatonic scale blended with the Bb Blues scale to capture the “sweet and sour” blues aesthetic.
Difficulty Rating 2/5: The 12-bar blues framework and standard diatonic substitutions provide a predictable and accessible foundation for developing jazz improvisers.
