Bass harmonization with modulation

Hi Davi, we don't do Harmony homework here; try doing it on your own and posting your version, and then at most you will be given indications where you made mistakes.

Even though the discussion is now old, I will try to offer some suggestions for harmonizing the bass in question (I am not presenting my own realization for now, hoping that some student might want to try their hand at it):

1) One should try to always maintain the movement of the voices in quarter notes so as not to stop the rhythm; to do this, one can use suspensions, neighbor notes, and passing notes.

2) Sometimes it is better to use fewer chords relative to the number of bass notes, i.e., by grouping more bass notes under a single chord where possible.

3) Do not trust the first solution found, but try to make several versions and then choose.
