An empath mime is a type of performer who uses music and dance movements to create and project emotion to an audience. Humans, Trill and members of certain other races and cultures are less receptive to the subtleties of these performances, but can use amplifying machinery (consisting of wire connections to the temples) in order to properly experience the empathic mime's art.
