Below is the description from Wikipedia....
"A cat piano or Katzenklavier (German) is a musical instrument designed by Athanasius Kircher. It consists of a line of cats fixed in place with their tails stretched out underneath a keyboard. Nails would be placed under the keys, causing the cats to cry out in pain when a key was pressed. The cats would be arranged according to the natural tone of their voices."
