William Byrd was an English composer. He was one of the greatest composers of his generation. Hiis name is sometimes spelled as Bird, Byrde, or Byred. The exact dates of his birth and death are not known, and even his place of birth (Lincoln) is merely guesswork, based on the fact that several families named Byrd lived in Lincolnshire during the 17th century. As a child, Byrd received music lessons from the renowned Thomas Tallis in the Chapel Royal in London. Byrd is part of the so-called virginalists. In 1563, he was appointed as organist of the cathedral in Lincoln, even though he must have only been around 20 years old and in 1572 he was appointed as organist of Chapel Royal together with Tallis. In 1575, again with Tallis, he received the rights to publish and sell his music by Queen Elizabeth I. In honour of the Queen, the two composers dedicated their Cantiones Sacrae in the same year.
On multiple occasions, Byrd was prosecuted in court. As a catholic, he was repeatedly prosecuted for the rejection of Anglicanism. Nonetheless, he remained in favour of the Queen, probably because he composed music for both religious branches. Moreover, he wrote both secular and sacred music, and both vocal and instrumental pieces.
