How does one play figured bass when the bass line contains ties?
For example, here are the first three measures of Vivaldi's "Filiae maestae Jerusalem" (sheet music source).
Do I understand correctly that in measure 1, since there are no numbers to indicate an inversion, one has to play a chord consisting of C, Es and G?
Does one play only F and As in measure 2 (while still holding down the C key)? Or does one release and press again the C key in addition to F and As in measure 2? (In which case - why is there a tie between those two C-s?)
In the first half of measure 3, does one press no new keys and just continue holding C, F and As? Continue holding only C? Continue holding C, release F and As and play Es and G again?
