Daisy is captivating and magnetic, and people want to be near her as a result of her charm and beauty. Nick says of her, at their first meeting after several years, that she has
[...] the kind of voice that the ear follows up and down, as if each speech is an arrangement of notes that will never be played again. Her face was sad and lovely with bright things in it, bright eyes and a bright passionate mouth, but there was an excitement in her voice that men who had cared for her found difficult to forget: a singing compulsion, a whispered "Listen," a promise that she had done gay, exciting things just a while since and that there were gay, exciting things hovering in the next hour.
She is attractive in almost every way; even her voice has a particular beautiful quality to it that draws people in. She seems to convey an excitement that inspires people to listen closely to her, to want to get closer to her. Her voice seems to suggest that she has been having fun quite recently and that she is going to be having fun again soon and that her hearers can partake of that fun themselves by remaining near her. Daisy even makes Nick feel as though he is the person she most wanted to speak to in these moments. She makes people feel like they can share in her good fortune and liveliness and vivacity.
