John Dowland (1563 - buried February 20, 1626) was an English composer, singer, and lutenist. He is best known today for his melancholy songs such as "Come, heavy sleep" (the basis for Benjamin Britten's Nocturnal), "Come again", "Flow my tears", "I saw my Lady weepe" and "In darkness let me dwell", but his instrumental music has undergone a major revival, and has been a source of repertoire for classical guitarists during the twentieth century.
