Nov 7, 2009: Rock Concert

[xoxoxoBruce]

Did you know the first rock concert was held right here in Pennsylvania?

In 1890, J.J. Ott gave a remarkable concert for the Buckwampum historical society. What made the concert remarkable wasn't the music being played but the instrument Ott was playing. The instrument was made of stones that made "clear, bell-like tones" when struck by a hammer. You might say it was the first rock concert.

Granted, they're not real pretty like Bryce Canyon ,or something, but they are sonorous. :p

Ott procured the musical rocks from a nearby boulder field in Upper Black Eddy, Pennsylvania. Known today as Ringing Rocks Park, the rock field occupies 7 acres of an otherwise wooded area, and is over 10 feet deep with boulders.

It would be a great place to film, Chain-Gang: The Musical.
But why do these particular rocks ring so nicely?

Only about a third of the rocks ring, and for a long time why the rocks rang at all was unclear. However, in 1965 a group of scientists crushed, broke, and sliced the rocks. After performing numerous tests, they found that while all the rocks do in fact ring, they often do so at tones lower than the human ear can perceive. Interactions between these low tones create any audible sounds. However, the exact mechanism by which they ring still remains elusive, and it may have to with the freeze-thaw cycle that helped created the boulder field in the first place.

So rigorous, peer reviewed, scientific examination, has come up with.... Damifino.
