Oh my, yes it will. One of the exercises I do is to play a melody with bass roots or other chord tones, as convenient.
However, this is a skill that takes some real understanding of theory (or an innate sense of what is happening musically). So for now, I would recommend learning a melody (either by reading standard musical notation well or by having a great ear), and trying to play that melody with chord roots. That's a pretty advanced concept, however.
To answer your question of How? - It always does the brain and ear good to hear intervals. But for those intervals to make sense (your ear will hear things as "normal" but until you understand the chord functionality, the reasons why it sounds familiar to your ear will remain a mystery), you need to understand Major/minor key chord structure.
Sorry if this sounds like a run-around. Learning music theory and actually understanding how to soundly apply it to your playing takes anywhere from a year to 20 years.
