It is supposed to be a joyful piece, even at a wedding! Unfortunately, the modern traditional classical interpretations are not true to the original intent of Baroque, classical and even romantic composer's wishes and intents!
That's where the specialist field of Early Music tries to take up the slack!
I guess the people that made this piece popular were not studying their music history well :)
This is where we see the importance of studying music history, to understand what the composer actually wanted portray in their music, as well as to be able to use that knowledge in performance. ^_^
