The church is affiliated to the Royal School of Church Music and choir members are encouraged to work towards the RSCM training schemes, especially the Dean's and Bishop's Awards.

In the church's early days each of the various guilds had their own organ but the guilds were suppressed in 1547 and by 1589 all existing organs in the church had been disposed of.

The church was subsequently without an organ for more than a century and a quarter during Puritan days, until Christian Smith was engaged to build one in 1717. Some of Smith's pipes still survive in the present instrument but, over the years, various builders have had a hand in its development, namely Nicholls, Hill, Bishop, Brindley, Norman & Beard and Henry Willis. The last major rebuild was in 1940 by Harrison & Harrison of Durham. In 1987, Harrisons carried out a restoration making some slight tonal changes and taking advantage of modern solid-state technology to increase the facilities.  In April 2007, they carried out some routine maintenance and cleaning, and up-graded the combination capture system to include 64 separate channels. The number of general pistons was increased from three to eight. It has three manuals and pedals, with 41 speaking stops and 12 couplers. The action is electro pneumatic.
 

The Chamber Organ is a ‘Premier’ model built by the firm of Cousans (Lincoln) Ltd in the 1960s. It is used for more intimate choral performances, where the main organ is not always appropriate, and with an orchestra, as a continuo organ.
