Nalargon

The Nalargon or Red Ball Jett keyboard was a keyboard instrument similar to an organ. Circular in shape, the player—known as a Nalargonist—would sit in the center of the instrument, depressing any combination of the 21 keys. Air intake was to the player's left, while the output speaker was on their right. Between the base of the organ and the keyboard were air outlet pipes.

Max Rebo was known to play a Nalargon.
