- Employs a #I°7 (B°7) chromatic passing chord to connect the tonic Bbmaj7 to the ii (Cm7), creating the standard “walking” bass movement found in Great American Songbook standards.
- Utilizes a minor ii-V (Am7b5 to D7) to target the relative minor (Gm7), providing a brief diatonic shift that adds emotional weight before returning to the major tonality.
- Features a secondary ii-V (Fm7 - Bb7) to tonicize the IV chord (Eb6), a common device used to expand the harmonic palette beyond the home key.
- Incorporates a V/V (C7) leading into a standard ii-V-I turnaround, reinforcing the cycle of fourths and strengthening the final resolution to Bb major.
Improvisation Focus Bb Major Bebop scale, with specific emphasis on using the b3 (Db) as a passing tone to navigate the B°7 to Cm7 transition.
Difficulty Rating 2/5: The predictable harmonic rhythm and reliance on standard ii-V-I sequences make it an accessible entry point for learning how to play over diminished passing chords.
