Ringing Rocks are rocks that have the property of resonating like a bell when struck, such as the Musical Stones of Skiddaw in the English Lake District as well as the stones in Ringing Rocks Park, in Upper Black Eddy, Bucks County, Pennsylvania USA and the Bell Rock Range of Western Australia. Ringing rocks are also known as sonorous rocks or lithophonic rocks, as used in idiophonic musical instruments called lithophones.
