Thomas Ravenscroft (c. 1582-1635) was an English music theorist, composer, editor, and collector. He composed Pammelia, the first English printed collection of rounds and part songs which was published in 1609, followed by Deuteromelia (1609) and Melismata (1611). It is likely that many of the pieces published were popular many years before Ravenscroft actually collected them.
