Pipe Organ

Nowadays a pipe organ has a bellows powered by an electrical motor.

The bellows pushes air through the pipes to sound them in much the same way as one blows into a whistle.

Before electrical motors, at least one person was required to pump manually the bellows of a pipe organ.

The more pipes an organ had, the greater its need for pressurized air; this would be supplied by adding more bellows and more persons to pump the additional bellows.

The Great Organ of Notre Dame de Paris required as many as twenty persons to pump its bellows by hand.

Here is a video of a pipe organ still pumped by hand. Click on the image below to view and hear it.
