I'm not trying to pick fights either. I'm not trying to convince I'm right and someone else is wrong either. I'm just calling it as I see it, after thinking about it for 20+ years. There are many more wrong ways to play changes than there are right ways. This has a lot to do with rules that come out of a long history of music, from classical to folk, jazz, pop. In this case of walking bass lines it is not, as you stated, a note within a bass line isn't played in a vacuum. It has to fit with the environment, and its own melodic structure. But the melodic structure makes rules of its own as it progresses. So for me, in the example I gave, the root on the 1 was breaking those rules. I've heard lines in which going from the 7 of a dominant chord to the 1 of a tonic worked. And that also was a result of a strong melody that worked in its environment. Tell me how that is narrow minded?
