The piece is 77 minutes in length, a full-concert work. Passing is performed by seven dancers and four musicians onstage (cello, guitar, accordion, clarinet, flute, keyboard, voice). It features a set of hand-netted linen forms, created by Tracy. These forms represent the veils between the worlds, which part when a being is passing. When they part, one enters what Celts call the Thin Place. It is a place of transformation, of spirit, of soul. One may be accompanied to this place by a loved one in the living world and/or beckoned by one beyond.
