Just to be clear, I'm using "chromatically" to mean a chromatic scale. I'll use a descending chromatic movement int the following example. This works so wonderfully on guitar. Say you have a circle of fifths starting with C7 F7 Bb Eb etc. The third and seventh of the C7 chord are the notes E and Bb. Moving those two notes down a half step gives you Eb and A which are the seventh and third of F7. Moving those two down a half step gives you D and Ab which are the third and seventh of Bb. Moving those to down gives you Db and G which are the seventh and third of Eb7. And on and on all the way around the circle. It is interesting and clever in itself but not overwhelmingly musical. But as a guide or principle for soloing or orchestrating, it becomes more useful. For example, playing a guitar solo, one could emphasize the chord changes by playing either the third or seventh (or both together) and moving it down a step right as the chord changes, like in a blues when it goes from I to IV. You could play any variety of notes before or after and get as far out as you want and then bring it back to earth right at the chord change by playing 2 notes or 2 pairs of descending notes. Hope this makes sense.
