A tibia is a sort of organ pipe that is most characteristic of a theatre organ.
Tibia pipes are generally made of wood, stopped, from 16' (Occasionally 32') with the top octave pipes (above 1/2', or 6" made of metal, stopped, and pipes from 1/4', 3" made of metal and open.
The mouth is cut very high, and the pipes have little harmonic development - the sound approaches that of a sine wave.
There is usually a tremulant on the wind for Tibia pipes - the increase and decrease of wind pressure gives "life" to the sound.

Woodwind instruments are a family of musical instruments within the more general category of wind instruments. Common examples include flute, clarinet, oboe, saxophone, and bassoon. There are two main types of woodwind instruments: flutes and reed instruments. What differentiates these instruments from other wind instruments is the way in which they produce their sound. All woodwinds produce sound by splitting an exhaled air stream on a sharp edge, such as a reed or a fipple. A woodwind may be made of any material, not just wood. Common examples include brass, silver, cane, as well as other metals such as gold and platinum. Occasionally woodwinds are made out of earthen materials, especially ocarinas.
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.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones, each played with its own keyboard, played with the hands on a keyboard. The organ is a relatively old musical instrument, dating from the time of Ctesibius of Alexandria, who invented the water organ. It was played throughout the Ancient Greek and Ancient Roman world, particularly during races and games. During the early medieval period it spread from the Byzantine Empire, where it continued to be used in secular (non-religious) and imperial court music, to Western Europe, where it gradually assumed a prominent place in the liturgy of the Catholic Church. Subsequently it re-emerged as a secular and recital instrument in the Classical music tradition.
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 theatre organ is a distinct type of pipe organ originally developed to provide music and sound effects to accompany silent films during the first 3 decades of the 20th century.
The water organ or hydraulic organ is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source or by a manual pump. Consequently, the water organ lacks a bellows, blower, or compressor.
A flue pipe is an organ pipe that produces sound through the vibration of air molecules, in the same manner as a recorder or a whistle. Air under pressure is driven through a flue and against a sharp lip called a labium, causing the column of air in the pipe to resonate at a frequency determined by the pipe length. Thus, there are no moving parts in a flue pipe. This is in contrast to reed pipes, whose sound is driven by beating reeds, as in a clarinet. Flue pipes are common components of pipe organs.
An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air is driven through it. Each pipe is tuned to a specific note of the musical scale. A set of organ pipes of similar timbre comprising the complete scale is known as a rank; one or more ranks constitutes a stop.
A tremulant is a device on a pipe organ which varies the wind supply to the pipes of one or more divisions. This causes their amplitude and pitch to fluctuate, producing a tremolo and vibrato effect. A large organ may have several tremulants, affecting different ranks (sets) of pipes. Many tremulants are variable, allowing for the speed and depth of tremolo to be controlled by the organist. The tremulant has been a part of organ building for many centuries, dating back to Italian organs of the sixteenth century.
The organ in St. Jacobi Church, Hamburg, was built in 1689 – 1693 by the renowned organ builder Arp Schnitger. The organ boasts four manuals and pedal with 60 stops -- of which 15 are reeds -- and totalling approximately 4000 sounding pipes. All in all, from the organ's original installation and its condition today not much of its conception has changed. The old pipework and the prospect pipes have been preserved in almost original format. This is the largest organ in existence from before 1700 and is one of the most eminent Baroque instruments that have been preserved.
The music of ancient Rome was a part of Roman culture from the earliest of times. Songs (carmen) were an integral part of almost every social occasion. The Secular Ode of Horace, for instance, was commissioned by Augustus and performed by a mixed children's choir at the Secular Games in 17 BC. Music was customary at funerals, and the tibia, a woodwind instrument, was played at sacrifices to ward off ill influences. Under the influence of ancient Greek theory, music was thought to reflect the orderliness of the cosmos, and was associated particularly with mathematics and knowledge.
A reed pipe is an organ pipe that is sounded by a vibrating brass strip known as a reed. Air under pressure is directed towards the reed, which vibrates at a specific pitch. This is in contrast to flue pipes, which contain no moving parts and produce sound solely through the vibration of air molecules. Reed pipes are common components of pipe organs.
The High Tide Organ is a tidal organ 15 metres tall constructed in 2002 as part of "The Great Promenade Show" series of sculptures situated along Blackpool's New Promenade in the UK. The artwork, described as a "musical manifestation of the sea", is one of a few examples of a tidal organ; others include the San Francisco Wave Organ and the Sea Organ in Croatia.
The Boardwalk Hall Auditorium Organ 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.
Gedackt 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".
This article describes the process and techniques involved in the tuning of a pipe organ. Electronic organs typically do not require tuning.
A Tibia Clausa is a type of pipe organ pipe. It is a large-scale, stopped wood flute pipe, usually with a leathered lip. The rank was invented by Robert Hope-Jones. Tibia Clausas provides the basic foundation tone of the organ with few overtones or harmonics. The Tibia Clausa is arguably the most important rank of pipes in a theatre pipe organ, with some organs having as many as 5. The stop shares similarities with the Bourdon and the Gedackt found in some church pipe organs. In the 18th and 19th centuries, Tibia Clausa was sometimes used as an alternate name for Doppelflöte. Most tibias are made from wood, as by Wurlitzer etc., although examples of metal tibias may be found made by the John Compton Organ Company.
Dome Pipe Organ, the second largest pipe organ in Latvia, is located in Riga Cathedral. The largest mechanical pipe organ in Latvia is located in Liepāja Holy Trinity Cathedral.
Casavant Frères Ltée. Opus 1841 is a pipe organ built by the famous Casavant Frères of Saint-Hyacinthe, Quebec. The organ was first completed in 1911 as Casavant Brothers - Opus 452 for St. Andrew's Presbyterian Church at 40 Bentinck Street, Sydney, Nova Scotia, Canada. St. Andrew's later became St. Andrew's United Church and is now the Highland Arts Theatre.
