 It is used in a number of American Style ballroom dances: rumba, waltz, bronze-level foxtrot.
 While it can be performed individually, it is usually done with a partner.

The minuet step is the dance step performed in the dance minuet.
 It "is composed of four plain straight Steps or Walks, and may be performed forwards, backward, sideways, &c." or in a square.
 The steps are often referred to by direction to distinguish them.
 "A Movement, or Sink and Rise, being added to the first Step of the three belonging to the Minuet Step, produces a Bouree; and the like to the fourth and last a Half Coupee, which together compose what is commonly called the English Minuet Step" .
