While the elements of Harry Bertoia’s sculpture are abstract, his inspiration comes from nature. A memory of wheat fields swaying in the breeze and the intriguing notion of a mythological Aeolian harp activated by the winds inspired Bertoia to create his “sounding sculpture” fountain. Installed in two parts, each segment of the artwork consists of black granite bases supporting brass plates, from which rise rows of flexible rods of thin copper. Wind currents cause the rods to vibrate at various frequencies according to their lengths, creating pleasing musical sounds.
