John Wynne's untitled installation for 300 speakers, pianola and vacuum cleaner is at once monumental, minimal and immersive. It uses sound and sculptural assemblage to explore and define architectural space and to investigate the borders between sound and music. There are three interwoven sonic elements: the ambient sound of the space in which it is installed, the notes played by the piano, and a computer-controlled soundtrack of synthetic sounds and gently manipulated notes from the piano itself. Because none of these elements are synchronised, the composition never repeats. The music punched into the paper roll is Franz Léhar's 1909 operetta Gypsy Love, but the mechanism has been altered to play at a very slow tempo and the Pianola modified to play only the notes which most excite the resonant frequencies of the gallery space in which it is installed.
