Variatio 19. a 1 Clav.

Beethoven tells you what it's like to be Beethoven and Mozart tells you what it's like to be human. Bach tells you what it's like to be the universe.
Douglas Adams (author)

Like almost all Baroque music it's all based on Dance rhythms - the cello suites and the suites in the partitas are filled with Gigues, Sarabandes and Allemandes which spring from dance modes of the time and beg to be danced to.
Mark Morris

Bach is Dance music - even in pieces like the preludes and fugues there are minuets, bourees, gigues, passepieds - all the dances are there, you just have to recognise them.
