John Dunstable

English composer John Dunstable (also spelled Dunstaple) was a major transitional figure between the medieval and Renaissance and the main proponent of what the French called the Contenance Angloise. He first made his mark in Canterbury during celebrations of the English victory at Agincourt. From the 1420s, he served in both England and France, on the English side to Joan of Navarre and the Duke of Bedford; in France, to the Plantagenets. He was also a noted astronomer. Almost none of Dunstable's music survives in England; however, copies are widespread throughout continental Europe, circulating as far as Russia.
