The organ at Chester Cathedral has a total of 3,800 pipes. It is one of the largest organs in the UK and features a wide range of sounds, making it a significant instrument for both worship and concerts. The organ was extensively restored and renovated in recent years, enhancing its musical capabilities.
Here is everything you need to know on the organ http://www.cathedral.org/cathedral/music/greatorgan.shtml The present main console is four manuals of 61 keys each, so the total is 244 manual keys. There are 32 pedal keys.
There is no limit to the number of pipes that an organ may have. The only factors that may pose a limitation are space and funding. The organ with the largest number of pipes is in Boardwalk Hall Atlantic City, NJ. It has 33,114 pipes.
As the vast majority of pipe organs are custom designed there is no one, definitive answer. A small, hand pumped, table top organ ("or Portative") might have as few as 25 pipes - or two octaves. The common, medium sized church organ averages around 1,000 pipes. Large organs can have upwards of 10,000 pipes. The two largest, the Wanamaker Organ and the Atlantic City Convention Hall Organ have 28,543 pipes and 33,114 pipes respectively.
IOW? A rank can have anything from 49 to 97 pipes depending on whether it is a straight or unit rank. There are even some short ranks that have fewer than 49 pipes. Ranks in the pedal divisions will have 32 pipes in a straight organ and that number plus multiples of 12 in a unit organ. As for the 14,000 pipe organ, a rough idea will be that number divided by 61. It's probably around 250 ranks when you take into account pedal ranks.
The number can vary greatly ... anywhere from a couple dozen to thousands upon thousands in any one pipe organ installation. The largest 100% playable pipe organ in the world, the Wanamaker organ in Philadelphia, contains 28,522 speaking pipes. One of the most famous organs in the world, The Mormon Tabernacle Organ contains 11,623 pipes.
That would be the Pipe Organ
The organ I play at an Episcopal (Anglican) church has 2,900 pipes, which is actually just about medium-sized (if there is such a measurement). The smaller theater organs I've played have about 1,000. The smaller church organ down the street has about 2,000.
London has many cathedrals, including St Paul's Cathedral, Westminster Cathedral, Southwark Cathedral and St George's Cathedral.
A reed organ has "free reeds" much like those in a harmonica. These have no resonators and require little space. A pipe organ uses pipes, which can be categorized in to two groups; Flues and reeds. Flues are simply whistles - no moving parts. reed pipes contain a brass tongue but unlike a reed organ they beat against a flat surface with an opening - the "shallot" upon which a resonator is mounted. The majority of pipes are flue pipes. Many small pipe organs have no reed pipes.
