The pipe organ is a musical instrument that produces sound by driving pressurised 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, volume, and construction throughout the keyboard compass. Most organs have many ranks of pipes of differing pitch, timbre, and volume that the player can employ singly or in combination through the use of controls called stops.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones. The organs have usually two or three, up to five, manuals for playing with the hands and a pedalboard for playing with the feet. With the use of registers, several groups of pipes can be connected to one manual.
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".
A pedalboard is a keyboard played with the feet that is usually used to produce the low-pitched bass line of a piece of music. A pedalboard has long, narrow lever-style keys laid out in the same semitone scalar pattern as a manual keyboard, with longer keys for C, D, E, F, G, A, and B, and shorter, raised keys for C♯, D♯, F♯, G♯ and A♯. Training in pedal technique is part of standard organ pedagogy in church music and art music.
A theatre organ is a type of pipe organ developed to accompany silent films, from the 1900s to the 1920s.
A manual is a musical keyboard designed to be played with the hands, on an instrument such as a pipe organ, harpsichord, clavichord, electronic organ, melodica, or synthesizer. The term "manual" is used with regard to any hand keyboard on these instruments to distinguish it from the pedalboard, which is a keyboard that the organist plays with their feet. It is proper to use "manual" rather than "keyboard", then, when referring to the hand keyboards on any instrument that has a pedalboard.
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards, and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone.

The Boardwalk Hall Auditorium Organ, known also as the Midmer-Losh and the Poseidon, is the pipe organ in the Main Auditorium of the Boardwalk Hall in Atlantic City, New Jersey, built by the Midmer-Losh Organ Company. It is the largest organ in the world, as measured by the number of pipes.
The pipe organ is played from an area called the console or keydesk, which holds the manuals (keyboards), pedals, and stop controls. In electric-action organs, the console is often movable. This allows for greater flexibility in placement of the console for various activities. Some very large organs, such as the van den Heuvel organ at the Church of St. Eustache in Paris, have more than one console, enabling the organ to be played from several locations depending on the nature of the performance.
Brighton and Hove has numerous notable pipe organs, from the small early 19th-century organs to the large 20th-century instruments in the large churches.
The Organ Reform Movement or Orgelbewegung was a mid-20th-century trend in pipe organ building, originating in Germany. The movement was most influential in the United States in the 1930s through 1970s, and began to wane in the 1980s. It arose with early interest in historical performance and was strongly influenced by Albert Schweitzer's championing of historical instruments by Gottfried Silbermann and others, as well as by Schweitzer's opinion that organs should be judged primarily by their ability to perform with clarity the polyphonic Baroque music of J. S. Bach (1685–1750). Concert organist E. Power Biggs was a leading popularizer of the movement in the United States, through his many recordings and radio broadcasts. The movement ultimately went beyond the "Neo-Baroque" copying of old instruments to endorse a new philosophy of organ building, "more Neo than Baroque". The movement arose in response to perceived excesses of symphonic organ building, but eventually symphonic organs regained popularity after the reform movement generated excesses of its own.
