Thomas Morley (1557 or 1558 – early October 1602) was an English composer, theorist, singer and organist of the Renaissance. He was one of the foremost members of the English Madrigal School. He was also involved in music publishing, and from 1598 up to his death he held a printing patent (a type of monopoly). He used the monopoly in partnership with professional music printers such as Thomas East. According to Philip Brett and Tessa Murray, Morley was 'chiefly responsible for grafting the Italian shoot on to the native stock and initiating the curiously brief but brilliant flowering of the madrigal that constitutes one of the most colourful episodes in the history of English music'.
