Isamu Noguchi employed sound as a sculptural material in two works. The first of these was a 1933 design for an illuminated Musical Weathervane, and the other was a 1950 proposal for a memorial Bell Tower for Hiroshima. Designed during Noguchi's first visit to Japan after the Second World War, this tower was to be a seventy-foot tall open structure from which huge bells would be suspended, to toll mournfully in the wind.
