William Byrd (c.1539/40 or 1543 – 1623,) was an English composer of the Renaissance. He wrote in many of the forms current in England at the time, including various types of sacred and secular polyphony, keyboard (the so-called Virginalist school), and consort music. He produced sacred music for use in Anglican services, although he himself became a Roman Catholic in later life and wrote Catholic sacred music as well. With John Bull, Byrd was been one of the most genial and modern composers of the ancient music.
The Lady Montegle's Paven is dedicated to an English noblewoman (Lady Mary Brandon, Baroness Monteagle), the daughter of Charles Brandon, 1st Duke of Suffolk, by his second wife, Anne Browne. The Pavana is taken from the "Fitzwilliam Virginal Book" (1562/1612) and is divided in six different sections.
