In chord voice-leading, the bass note has the most flexibility on how/where to move. While there are some strong suggestions to keep bass motion at intervals small – like under a perfect-fourth – there is certainly more leeway for a bass not in a chord to make large intervallic leaps… as opposed to inner voices and melody, which should move stepwise.
Now, what if these roles were reversed? Given, jumpy upper voices in a chord can sound a bit out of place; however, having the bass line be crafted like a melody can yield cool results of a smooth transition from one chord to another.
Take a chord progression for example:
After deciding on a progression, my next piece of advice is to find common tones between the chords as well as adjected notes by at most a minor third (though M3 and P4 can work, too). Make a note of all the possibilities. From there, write a melody within the harmonic rhythm that is smooth and overall stepwise in motion. Then, let those be the root positions and/or inversions of the chords you previously chosen.
Rest is there for you from there on out on how to play around with the upper voices and melody, but now you have a melodic line in the bass that can be used as a motif a basis for variation.
