The Great Stalacpipe Organ. This unique, one-of-a-kind instrument was invented in 1954 by Mr. Leland W. Sprinkle of Springfield, Virginia, a mathematician and electronic scientist at the Pentagon. He began his monumental 3 year project by searching the vast chambers of the caverns selecting stalactites to precisely match a musical scale. Electronic mallets were wired throughout the caverns and connected to a large four-manual console. When a key is depressed, a tone occurs as the rubber-tipped plunger strikes the stalactite tuned to concert pitch. (scroll down for mp3).
