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. 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 ...
An organ stop is a component of a pipe organ that admits pressurized air (known as wind) 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" (admitting the passage of air to certain pipes), or "off" ( stopping the passage of air to certain pipes).
The pipe organ is a musical instrument that produces sound by driving pressurised air (called wind) 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.
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.
Registration is the technique of choosing and combining the stops of a pipe organ in order to produce a particular sound. Registration can also refer to a particular combination of stops, which may be recalled through combination action .
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.
Bourdon, bordun, or bordone normally denotes a stopped flute type of flue pipe in an organ characterized by a dark tone, strong in fundamental, with a quint transient but relatively little overtone development. Its half-length construction makes it especially well suited to low pitches, and economical as well.
A cornet, or Jeu de Tierce, is a compound organ stop, containing multiple ranks of pipes. The individual ranks are, properly, of flute tone quality but can also be of principal tone. In combination, the ranks create a bright, piquant tone thought by some listeners to resemble the Renaissance brass instrument, the cornett .
Pipe organs, which use air moving through pipes to produce sounds. The air is supplied by bellows, an electric motor or water. Since the 16th century, pipe organs have used various materials for pipes, which can vary widely in timbre and volume. Increasingly hybrid organs are appearing in which pipes are augmented with electric additions;
The organ has some special characteristics: the principal pipes have generally a narrow scaling, which gives them a restrained dry tone. It has long been puzzling as to why Gabler found it acceptable to scale the pipes considerably narrower than could have been with such a great space to be filled.
