Horizontal parentheses traversing one note to another in sheet music

What are these parentheses trying to tell me?  Some come in pairs (see A) Others connect notes from an overhead position (see B), some from a position below the notes (see C), and some are parentheses within parentheses (see D).  If there’s an explanation of them in the lesson book, I failed to see it.
