Instrument boasts 3,500 pipes

The word "organ" derives from the Latin word "organum," the earliest instrument ancestor of the pipe organ. The organum was used in ancient Roman circus games. \nThe major parts of a pipe organ are the pipes, console and blower. The blower supplies the air to the instrument. \nThe Auer Hall organ has four keyboards: three controlled by the hands and one controlled by the feet. \nThe three manual keyboards are identified as the "swell," the "great" and the "choir" in descending order. \nIn its completion, the Auer Hall organ would have 3,489 pipes and 52 total stops.
