Song for Ghost Travellers is a score for twelve pigeons and three musicians. Inspired by the Chinese tradition of attaching spherical flutes to pigeons, this performance explores ideas of randomness and the emergence of natural organisation through the patterns of flying birds and the movements of trains inside a railway station.

Through a slight alteration the pigeon is turned into the actor of a musical score: each pigeon carries a specially tuned flute which produces a sound when the bird is flying. Following a notated score, three musicians on the ground accompany the air-bound harmonies produced by the birds and combine them with the choreography of trains in the station.
