At first glance these progressions seem to have a lot of similarities, i.e. a I-IV-V in C uses C, F and G as major chord roots. A V-ii-I in F uses C, G and F as major chord roots, except for the minor G chord. As a new bass player that doesn't stray too far from root, 3rd, 5th, and 7th, the notes I choose to play over these progressions are mostly the same. Besides the minor ii, and the order of the chords, what other significant differences are there? The feel of the songs is certainly different, and how tension builds and is resolved is probably not the same, but I haven't studied enough theory to say how or why, and I'm not skilled enough to develop a good walking bass line to fit the progressions or be able to choose the better chord transition notes. Are these progressions vastly different even though they use mostly the same basic notes? Discussion welcome.
