Rhosymedre is the name of a hymn tune written by the 19th-century Welsh Anglican priest John David Edwards. Edwards named the tune after the village of Rhosymedre in the County Borough of Wrexham, Wales, where he was the vicar from 1843 until his death in 1885. The hymn tune is seven lines long, with a metrical index of 6.6.6.6.8.8.8. It appears in a number of hymnals and is sung to a variety of words.
The tune was used by Ralph Vaughan Williams as the basis of the second movement of his organ composition Three Preludes on Welsh Hymn Tunes. This is probably best known as an orchestral arrangement by Arnold Foster published in 1938. The prelude has been arranged for other instruments or combinations of instruments, including solo piano, piano duet, clarinet choir and four recorders.
In 2008, to mark the 50th anniversary of the death of Vaughan Williams, Richard Morrison (chief music critic of The Times) arranged the piece for string quartet and solo tenor. The first performance took place in May 2008, with James Gilchrist singing the words of the hymn.
Rhosymedre is a village within the community of Cefn and the county borough of Wrexham, Wales.
The Anglican church, which was consecrated in 1837, is dedicated to St John the Evangelist, and is part of the Diocese of St Asaph. Former vicars include John David Edwards (vicar from 1843 to 1885), whose most famous hymn tune composition is Rhosymedre.
Rhosymedre Halt railway station served the village from 1906 to 1959.
