Why do we sing while saying viduy?
Throughout Yom Kippur everyone says viduy (confession) numerous times.
In the shuls that I have davened at (and I think most shuls), when everyone says it together during chazaras hashatz, there is a little niggun that is sung between phrases (after דברנו דופי, טפלנו שקר, etc.).
Viduy is the time when we say how we sinned in many different ways; why are we singing during this time?
