Big Bang Theory Theme

Big Bang Theory Theme, also known simply as The History of Everything, was written and performed by the Canadian band Barenaked Ladies. It was specially composed as the opening theme for the popular American sitcom The Big Bang Theory. The song humorously and simplistically summarizes the history and evolution of the universe, from the Big Bang to the development of human life and its achievements.

Key: G

Our whole universe was in a hot dense state,

Math, science, history, unraveling the mysteries,

"Since the dawn of man" is really not that long,
          C           D               G             D/F#       Em 
As every galaxy was formed in less time than it takes to sing this song.

It will pause and start to go the other way,

Australopithecus would really have been sick of us
   C                 D                       G            D/F#      Em 
Debating how we' re here, they' re catching deer (we' re catching viruses)
