Organ console. The console of the Wanamaker Organ in the Macy's (formerly Wanamaker's) department store in Philadelphia, featuring six manuals and colour-coded stop tabs.

Construction[edit] A pipe organ contains one or more sets of pipes, a wind system, and one or more keyboards. The pipes produce sound when pressurized air produced by the wind system passes through them. An action connects the keyboards to the pipes.
An organ stop can be one of three things: the control on an organ console that selects a particular sound; the row of organ pipes used to create a particular sound, more appropriately known as a rank; the sound itself; Organ stops are sorted into four major types: principal, string, reed, and flute.
A windchest is a component of a pipe organ on which the pipes sit. As the organist plays the instrument, the keys, stops, and windchest work together as a mechanism (called an 'action') to direct pressurized air (called 'wind') into the pipes, thus creating sound.
Common stop controls include stop knobs, which move in and out of the console, and stop tabs, which toggle back and forth in position. Some organs, particularly smaller historical organs from England, Spain or Portugal, [1] feature divided registers, in which there are two stop knobs for certain ranks.
The pitch of a rank of pipes is denoted by a number on the stop knob. A stop that speaks at unison pitch (the "native pitch" for that note; the pitch you would hear if you pressed that same key on a piano) is known as an 8′ (pronounced "eight foot") stop.
