- Utilizes a standard I-VI-ii-V cycle in Bb major, employing G7#9 as a high-tension secondary dominant to drive the resolution to Cm9.
- Employs “backdoor” chromaticism and side-slipping, specifically the Db9 to Gbmaj7 sequence, which creates temporary tonal ambiguity before returning to F13.
- Features repetitive, parallel dominant 13th chord oscillations (Ab13 to G13), common in big band writing to provide a modern, blues-inflected harmonic rhythm.
Improvisation Focus The Bb Blues Scale combined with Mixolydian patterns to navigate the frequent dominant chord substitutions.
Difficulty Rating 3 (Intermediate): The piece blends traditional bebop changes with rapid chromatic shifts and non-functional dominant chains that require quick harmonic processing.
