jig.

(1) A traditional dance of the British Isles, probably dating back to the 15th century. The word may be derived from the Old French verb gigner ('to leap', 'to gambol'). It is characterized by lively jumping steps, the only common feature of its many varieties. The best-known jig is the Irish, danced solo or by a couple to the accompaniment of the pipe and fiddle and usually in compound duple or triple time. The jig appears in the Fitzwilliam Virginal Book and other contemporary keyboard collections, with examples by Byrd, Bull, and Farnaby. Shakespeare mentioned the 'Scotch jig' in Much Ado about Nothing. See also gigue.

(2) From the 16th century to the 18th, the jig (or jigg) was also an often bawdy farce in rhyme, sung and danced to popular tunes, performed both in England and on the Continent.
