The Eton Choirbook (compiled 1490–1502) contains several works by Cornysh:
William Cornysh the Younger - also spelled Cornyshe, Cornishe or Cornish- was an English composer, dramatist, actor, and poet who lived between 1465 – 1523. In his only surviving poem, which was written in Fleet Prison, he claims that he has been convicted by false information and thus wrongly accused, though it is not known what the accusation was. He may not actually be the composer of the music found in the Eton Choirbook, as this may alternatively be by his father, also named William Cornysh. The younger Cornysh had a prestigious employment at court, as Master of the Children of the Chapel Royal; and being responsible for the musical and dramatic entertainments at court and during important diplomatic events such as at the Field of the Cloth of Gold in 1520; and visits to and from the courts of France and the Holy Roman Empire, which he fulfilled until his death. The Eton Choirbook (compiled 1490–1502) contains several works by Cornysh: Salve Regina, Stabat Mater, Gaude Virgo Mater Christi, and Ave Maria Mater Dei. Other sources refer to lost works: three Masses, another Stabat Mater and another Magnificat. Cornysh also produced secular vocal music and the notable English sacred anthem Woefully Arrayed.
