Fantasia on a Theme by Thomas Tallis

Thomas Tallis ( 1505 – 23 November 1585) was an English composer who occupies a primary place in anthologies of English choral music, and is considered one of England's greatest composers.
 He is honoured for his original voice in English musicianship.
 No contemporary portrait of Tallis survives: that painted by Gerard Vandergucht ("illustration"), dates from 150 years after Tallis died, and there is no reason to suppose that it is a likeness.
 In a rare existing copy of his black letter signature, the composer spelled his last name "Tallys."
Signum Records is a classical musical record label in the UK founded in 1997 around a then-ambitious project to make the first complete recording of the works of Thomas Tallis.
 The artists for the recording were the Chapelle du Roi, an ensemble of ten singers founded in 1994 by Alistair Dixon, also co-founder of the record label.
 The other fifty percent of the company was held by Floating Earth sound engineers.
 Since the Tallis project the label has grown to host many well known UK ensembles, including The Kings Singers, the Philharmonia Orchestra, Huddersfield Choral Society, Charivari Agreable, Tenebrae directed by Nigel Short, Voces8, Cantabile and the choir of Her Majesty’s Chapel Royal, who record at St James’s Palace, London.
Simon Brown was the director of music at King's College School in Cambridge from 1999-2014.
 and was the director of King's Voices from 2001 to 2013.
 He was a choral scholar in King's College Choir in the late 1970s, and since then has sung in the choirs of New College, Oxford, Winchester Cathedral, Westminster Abbey and Her Majesty's Chapels Royal (St James' Palace).
 His teaching career began at Bradford Grammar School in Yorkshire, and was followed by 12 years as Head of Academic and Choral Music at the Purcell School.
 His time at the Purcell School included conducting the youngest ever choir to sing Tallis' 40-part choral work "Spem In Alium".
Edward Paston (1550–1630), second son of Sir Thomas Paston, was a Catholic gentleman of Norfolk, a poet, and amateur musician living in the reign of Elizabeth I.
 He is an important figure in the musical history of England, his love of music driving him to acquire and copy musical manuscripts from some of the most important composers of the Renaissance, resulting in a unique performing collection of 16th-century house music that included works by William Byrd, Thomas Tallis, John Taverner, and Orlando di Lasso.
 He was especially interested in Byrd, and one of his books is the largest source of consort songs by that composer.
 Paston played the lute, creating a wide range of vocal settings and accompanying tablatures in partbooks that are still obtainable.
 As a young man he travelled extensively in Spain, being influenced by the Spanish (and Italian) form of tablature, as seen in his partbooks, rather than the generally used French form.
The Tallis Festival, hosted by Exmoor Singers of London, forms the Tallis Festival Choir for just one weekend every 12 to 18 months.
 The Festival always includes Thomas Tallis' Spem in Alium for 40-part choir, but in addition has commissioned new 40-part works by modern composers, as companion pieces to Spem in Alium.
 In 2007 the Festival was recognised by the BBC for its contribution to new music and highlights from the Festival were broadcast on BBC Radio 3 on 28 October 2007.
Arthur Henry Mann (16 May 1850, Norwich – 19 November 1929, Cambridge) was an English organist and composer of hymn tunes including "Angel's Story" which was originally written for the hymn 'I love to hear the story', but is also sung to the words 'O Jesus, I have promised.'
 He was most noted for his role as organist and director of music at King's College Chapel, Cambridge from 1876 until 1929, being the founder director of the world famous tradition of the Festival of Nine Lessons and Carols since its first performance in 1918.
 In 1888, he published his own edition of Thomas Tallis's Spem in alium.
 His edition, though flawed, was the first publication ever made of Tallis's famous motet in forty parts.
Spem in alium (Latin for "Hope in any other") is a 40-part Renaissance motet by Thomas Tallis, composed in c. 1570 for eight choirs of five voices each, considered by some critics to be the greatest piece of English early music.
 Along with Tallis's "Lamentations", H. B. Collins described it in 1929 as Tallis's "crowning achievement".
This is a list of compositions by the English composer Thomas Tallis (c. 1505–1585).
The Gyffard Partbooks (British Library Add.
 MSS 17802-5) (also spelled Giffard) are an important set of English Renaissance choral partbooks, containing pieces by composers such as Thomas Tallis and John Sheppard, as well as additional unnamed composers, which are not found in other sources.
Fantasia on a Theme by Thomas Tallis, also known as the Tallis Fantasia, is a work for string orchestra by the British composer Ralph Vaughan Williams.
 It was composed in 1910 and performed for the first time on 10 September that year at Gloucester Cathedral for the Three Choirs Festival.
 Vaughan Williams himself conducted, and the composition proved to be a major success.
 He revised the work twice, in 1913 and 1919.
 Performances generally run between 14 and 16 minutes.
