Galliard
(Wikipedia) The galliard (gaillarde, in French; gagliarda in Italian) was a form of Renaissance dance and music popular all over Europe in the 16th century. It is mentioned in dance manuals from England, France, Spain, Germany and Italy, among others.
Musical compositions in the galliard form appear to have been written and performed long after the dance fell out of popular use. In musical compositions, the galliard often filled the role of an after dance written in 6, which followed and mimicked another piece (sometimes a pavane) written in 4. The distinctive 6 beats to the phrase can still be heard today in songs such as "God Save the Queen".
