The pipe organ is a musical instrument that produces sound by driving pressurized air through the organ pipes selected from a keyboard. Because each pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre and volume throughout the keyboard compass. Most organs have many ranks of pipes of differing timbre, pitch, and volume that the player can employ singly or in combination through the use of controls called stops.
The Walt Disney Concert Hall at 111 South Grand Avenue in downtown Los Angeles, California, is the fourth hall of the Los Angeles Music Center and was designed by Frank Gehry. It was opened on October 24, 2003.

The hall is a compromise between a vineyard-style seating configuration, like the Berliner Philharmonie by Hans Scharoun, and a classical shoebox design like the Vienna Musikverein or the Boston Symphony Hall.
An organ stop is a component of a pipe organ that admits pressurized air to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; each can be "on", or "off".

Tracker action is a term used in reference to pipe organs and steam calliopes to indicate a mechanical linkage between keys or pedals pressed by the organist and the valve that allows air to flow into pipe(s) of the corresponding note. This is in contrast to "direct electric action" and "electro-pneumatic action", which connect the key to the valve through an electrical link or an electrically assisted pneumatic system respectively, or "tubular-pneumatic action" which utilizes a change of pressure within lead tubing which connects the key to the valve pneumatic.
The Wanamaker Grand Court Organ, located in Philadelphia, Pennsylvania is the largest fully-functioning pipe organ in the world, based on the number of playing pipes, the number of ranks and its weight. The Wanamaker Organ is located within a spacious 7-story Grand Court at Macy's Center City and is played twice a day Monday through Saturday. The organ is featured at several special concerts held throughout the year, including events featuring the Friends of the Wanamaker Organ Festival Chorus and Brass Ensemble.
The electro-pneumatic action is a control system by the mean of air pressure for pipe organs, whereby air pressure, controlled by an electric current and operated by the keys of an organ console, opens and closes valves within wind chests, allowing the pipes to speak. This system also allows the console to be physically detached from the organ itself. The only connection was via an electrical cable from the console to the relay, with some early organ consoles utilizing a separate wind supply to operate combination pistons.
