Thump.

A little-used 17th-century term for a primitive left-hand pizzicato, limited to open strings (see J. Playford: Musick’s Recreation on the Viol Lyra-way, London, 1669, and T. Ford: Musicke of Sundrie Kindes, London, 1607, where the last piece has the alternative title ‘Mr Richard Martin’s Thump’; the term is explained on sig.K2v and the thump is to be executed with the first or second finger of the left hand).
