What is DROP D tuning??? plz help

Can some1 tell me how to take standard tuning and tune to DROP D. My teacher did not teach me this...thanks peepz

:rock:

 

tune the bass string from E to D...its that simple...
EADGBe -> DADGBe

if you are familiar with relative tuning then tune 7th fret of your E with open A....instead of 5th fret of E and open A

 

Oh yes im familiar with that. Thanks guys. let me go try to play some godsmack now.
