Itzhak Perlman said of DeLay's pedagogic approach: "I would come and play for her, and if something was not quite right, it wasn't like she was going to kill me. She would ask questions about what you thought of particular phrases—where the top of the phrase was, and so on. We would have a very friendly, interesting discussion about 'Why do you think it should sound like this?' and 'What do you think of that?' I was not quite used to this way of approaching things."
