Player Piano was an installation made for Tate Britain's Family Day. It was housed in the 1500-1880 room and comprised an upright piano, two stones and a marimba made from scallop shells. The piece referenced paintings in the room and invited audiences to activate the various objects, sending the sounds around a 6 channel system and out into the huge resonant space. When touched the two rocks (taken from Millais' The Boyhood of Raleigh) disturbed the upright piano, causing it to emit rumbles and tumbling chords, and a central table on which children could doodle was also amplified, adding the sound of scribbling to the delicate sound-space.
