Andrew,
Thanks for posting this question, although I know you did it more for the benefit of others as you well know how…
The best way to outline the changes when improvising in a nutshell is:
1- Use the underlying chord’s arpeggio as the framework for your lines in each measure.
2- Begin most measures with a primary guide tone (3 or 7). If not, be sure to include them in the measure.
3- Use smooth voice leading (not more than a 3rd), when transitioning melodically speaking to a new chord.
For a detailed explanation please watch and re-watch “Guide tones and Voice Leading” in Module 1 and “Anatomy of a Bebop Line” in Module 2.
