Modern Square Dancing is a social activity where eight people form a square with 2 people on each side, then dance a series of movements as "called" by the square dance caller.  It is a healthy, recreational, fun activity.  It is often said that square dancing is "Friendship Set to Music".  Dancing is done to music from the 50's and 60's (eg. “Pink Cadillac”, “Bill Bailey”, Show and Broadway, Elvis Presley tunes, etc.), through to more modern numbers (eg. “Rolling in the Deep” by Adele, “All about that Bass” by Meghan Trainor), as well as earlier music periods.  Even some upbeat classical music is used!
