An Organist and Master of the Choristers is a title given to a Director of Music at a cathedral, particularly a Church of England cathedral. The tradition dates back to the Middle Ages. They are both the organist and the choirmaster.
As Organist and Master of the Choristers, they are primarily occupied with the training and conducting of the cathedral choir. The sub-organist or assistant organist usually plays at cathedral services, although they will also be expected to take over the choral duties if the organist is unavailable.
The longest serving Organist and Master of the Choristers was Andrew Goodwin, who retired from Bangor Cathedral on 31 October 2009. He had served there for 37 years. He was the master of the choristers when Aled Jones was in the choir.
