John Baldwin, a member of the choir of St Georges Chapel in Windsor, made transcripts of the music sung there in the 1570s and 1580s. His notes constitute one of the largest collections of Marian polyphony, written at the time of Henry VIII and Mary Tudor. The song texts honour Mary as the mother of God and the Virgin with her child. The British ensemble Contrapunctus, directed by Owen Rees, combines a powerful interpretation with pioneering study and exploration. They are currently artists in residence at Oxford University.
