My question today stems from me having difficulty assigning a roman numeral to a chord which either has a suspension (please see below)
Or when there is melodic motion in the bass (please see below)
In the first case (both examples in C major by the way), do we simply call this a vi chord and call it a day? Or, because the D in the soprano line is sounded, is this a viadd4 chord? Similarly, in the example with the C-D motion in the bass, is this just a I chord? Or is this a one chord that becomes something else--something that I wouldn't even know how to name?
