Bells The tower has a ring of twelve bells plus four semitone bells and a 4.1 tonne non-swinging bourdon. The current peal of 15 ringing bells were cast in 1928 by John Taylor & Co., of Loughborough, from the metal of the original ring cast in 1869. The bourdon bell was cast in 1869 and retuned in 1928. It is only used by the clock to strike the hours and sometimes tolls for special events. The ring is the sixth heaviest ring of twelve in the world; only the bells in the cathedrals of Liverpool, Exeter, York, and St Paul's in London, and of St Mary Redcliffe church in Bristol are heavier. The bells are also considered to be one of the finest toned rings ever cast, a close contender to York Minster. The bells hang in a wooden frame that was constructed in 1869 for the previous ring. Worcester Cathedral is unique in having a purpose-built teaching centre equipped with eight special training bells, linked to computers. Music Worcester Cathedral has three choirs: Worcester Cathedral Choir (the principal choir which has both boys' and girls' sections, normally working independently), Worcester Cathedral Voluntary Choir, and Worcester Cathedral Chamber Choir. All three were involved in the BBC broadcast of the midnight and Christmas morning services in 2007, with the boys and the girls of the Cathedral Choir, respectively, taking the lead in the two services. Since the 18th century, Worcester Cathedral Choir has taken part in the Three Choirs Festival, the oldest music festival in the world. The composer Edward Elgar spent most of his life in Worcestershire. The first performance of the revised version of his Enigma Variations – the version usually performed – took place at the cathedral during the 1899 Three Choirs Festival. He is commemorated in a stained glass window which contains his portrait. Worcester Cathedral has a long history of organs dating back to at least 1417. There have been many re-builds and new organs in the intervening period, including work by Thomas Dallam, William Hill and most famously Robert Hope-Jones in 1896. The Hope-Jones organ was heavily re-built in 1925 by Harrison & Harrison, and then regular minor works kept
