Pipe organ
The stops on an organ console give different sounds, like the instruments of an orchestra, and have names which tell the organist what kind of sound they will produce. The stops are usually to the left and right of the organist and they are pulled out (“drawstops” or “pulls” because they are “drawn” i.e. pulled). Some organs have “tab stops” or “rocker stops” which are in front of the player and can be rocked forwards and backwards for on/off.
