I think the music signifies as a way of Margaret telling William she was so injured by the Rake that it killed the baby that's why in the next song he asks if it was "a forest's son or a river's daughter". Also probably a reminder that William did let the Annan Water claim his life which sort of puts a damper on their reunion.
