So, this is the strangest keyboard that I have ever stumbled across.... EVER. It even makes the Optigan seem less zany by comparison. The insturment is called the Katzenklavier .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."
