For the Bach English Suites, what do the dances mean? How many dances are there? I m required to play two dances in my audition.?

There are six suites and each one is made up of a number of dances. For example, the first contains Prelude, Allemande, Courante I, Courante II, Double I, Double II, Sarabande, Bourrée I, Bourrée II, Gigue. So you would pick two of those.
