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.
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).
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 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;
Gedackt (also spelled gedeckt) is the name of a family of stops in pipe organ building. They are one of the most common types of organ flue pipe . The name stems from the Middle High German word gedact , meaning "capped" or "covered".
Wood and metal pipes of a variety of sizes are shown in this photograph. An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air (commonly referred to as wind) is driven through it. Each pipe is tuned to a note of the musical scale.
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.
