The organ presently in Lichfield Cathedral dates from 1861, the year that Gilbert Scott completed the refurbishment of the Quire. The organ was first placed in St Stephen's Chapel, situated on the east side of the North Transept. It is reported to have been a noteworthy instrument, not least because it sported the earliest full pedal specification of stops along continental lines in England.
In 1884 William Hill and Sons were contracted to rebuild the Organ. In fact, they replaced the majority of stops on the manual divisions, retaining much of Holdich's Pedal Organ. Towards the turn of the century its position in the chapel was felt to be increasingly undesirable. The console was placed in the North Quire Aisle which did not allow great rapport between the organist and the choir, and the sound of the organ had insufficient egress into the body of the Cathedral. In 1907 a new chamber was built outside the Cathedral above the North Quire Aisle, the glass was removed from the windows and the organ resited aloft in the position is occupies today. The organ was enlarged, and a new console provided in 1908.
Rebuilding took place again in 1974 by Hill, Norman, and Beard. Minor alterations were made to the Solo, Swell, Great and Pedal departments, and the Choir organ was completely remodelled. The most recent rebuild in 2000 by Harrison and Harrison saw the addition of the Nave organ, and a return of the Choir organ to a specification closer to the 1908 organ.
The 1908 organ had 63 speaking stops, and 3,774 pipes, this was augmented in the 1974 rebuild to 66 speaking stops and 4,064. The latest work on the organ gives the 2000 organ 80 speaking stops, and a noteworthy 5,038 pipes.
Before the 1908 rebuild, there are records of three earlier organs: Samuel Green's organ of 1789; George's Holdich's of 1861; and William Hill and Son's organ of 1884. Martyn Rawles has written a "very brief" history of the Cathedal organs going back to the fifteenth century, which is available to download here.
The organ is tuned to a sharp pitch, C=540 hertz.
