I came across the following chord progression, which I really like:
The iii4/2 chord adds a lot to the progression in comparison to the following:
I'm sure you could wrap your head around these progressions--I am just sharing the images for reference. My question: is there a reason why the first progression is more satisfying the the second? I looked at the root movement in the two progressions, and the iii-vi features movement of a descending fifth, which should sound stronger than that of the falling fourth in the iii4/2-vi. That's about as far as my analysis goes. I understand this my reaction to the chord changes is somewhat subjective, but can you see any technical reason I find the first progression more compelling/satisfying?
