This post got me thinking about root movement. It has been said time and again that root movement of an upward fourth and descending fifth are particularly satisfying, and obvious choices when working towards good voice leading. But are there situations in which a bass that moves by step is more appropriate? Sequences like the one below are what mostly come to mind (C maj):
But I can think of other examples . . . what about the chorus of Changes by David Bowie?
It looks something like this (also in C maj):
And it certainly is amazing. But wouldn't traditional music theory have pushed him to write a bass line that looks more like this (forgive me if this doesn't look pretty):
If anyone could elaborate on this concept (namely, the various effectiveness of stepwise bass vs. bass lines that follow the circle of fifths), then I would be very appreciative.
