Parry is considered one of the country 's most influential musicians and a key architect of the 19th Century English Musical Renaissance . The first known works by one of Britain 's finest composers , Sir Hubert Parry , who wrote the music for Jerusalem , are being sold at auction . The 70 documents , expected to fetch up to £50,000 , represent Parry 's earliest surviving work and include pieces written when he was an Eton schoolboy and at Oxford . Many of the pieces have never been played in public , but a premiere before the Prince of Wales , a champion of Parry 's music , is to take place in May . Parry is considered one of the country 's most influential musicians and a key architect of the 19th Century English Musical Renaissance . As well as Jersualem , he wrote many famous settings for English hymns , including Repton , a well-known tune for Dear Lord And Father Of Mankind . Parry 's setting of the anthem I Was Glad has been played at the Coronations of every Monarch since Edward VII and was performed at the Westminster Abbey wedding of Prince William and Kate Middleton , as well as the wedding of Prince Charles and Lady Diana in 1981 . In a BBC4 documentary about Parry 's music , Charles said : 'It gives you tingles up the spine and tears in your eyes . ' Parry 's version of The Magnificat And Nunc Dimittis In D , and an anthem entitled O Sing Unto The Lord , are considered the best of the cache and will be sung for the first time by the choir at Gloucester Cathedral . Leading institutions and potential buyers , including Prince Charles , have been sent details of the auction at Chorley 's , Gloucester , on May 19 . It is an appropriate venue because Sir Charles Hubert Hastings Parry ( 1848-1918 ) grew up just two miles from Gloucester , where he learned to play the organ . Leading institutions and potential buyers , including Prince Charles , have been sent details of the auction at Chorley 's , Gloucester , on May 19 . Adrian Partington , the cathedral 's director of music , who examined all the manuscripts and chose the two pieces for the premiere , said : 'The pieces are beautifully well-written for his age and show a talented young composer , but they are not exceptional . I think he was writing stuff for his chums to perform at Eton and Oxford and he did it in a hurry . 'They were probably only performed informally around the piano and I suspect he just forgot about them , which is why they have been gathering dust for all these years . 'But the seeds of a great composition like Jerusalem can be found in this student work . These are beautifully shaped tunes , logical harmony and very exact but imaginative setting of the words . ' Some are incomplete or jottings , but there are some important compositions which until recently were kept in storage by one of Parry 's distant relatives . In later life , Parry went on to teach and later run the Royal College of Music in London , which has an archive of his work . Dr Peter Horton , a librarian at the college , said : 'The new documents are interesting because they are his early works and one can see from them how Parry 's work developed . '
